You need not worry about what box is picked - we are told one ball is gold. This rules out box #3 on the list.
Out of the two boxes remaining, remove one gold ball from each.
Oh look! There's a gold ball left in box 1, and a silver ball in box 2.
The odds are 50/50 that the NEXT ball is gold. Do not let the other four balls confuse you.

This is correct, You must either have th ebox with 2 gold balls, or the box with 1 gold and 1 silver.
>Out of the two boxes remaining, remove one gold ball from each.
That's not what happens in the question. In the question, you've randomly seleted 1 box from 3. and then randomly plucked a ball from that box. The ball was gold.
>Oh look! There's a gold ball left in box 1, and a silver ball in box 2.
That means nothing. You are working with a single box now, not 2 boxes from which you have removed 2 gold balls.
>The odds are 50/50 that the NEXT ball is gold.
Incorrect.
The answer is 2/3
Here is the reason:
You are TWICE AS LIKELY to have the all gold box as you are to have the gold/silver box due to the fact that the first ball plucked from the box was gold.
Answer = 2/3

Except it isn't. This retard doesn't seem to understand that you can't see inside the boxes, and that you only take out 1 gold ball, not 2. So, here's what actually happens. You take out a gold ball. You immediately know that box #3 is eliminated because it has no gold balls at all. You're left with 3 balls in total over 2 boxes, with 2 gold balls left from them. It doesn't matter which box you choose from, the probability is going to be 2/3.

Correct.
>>677663361
50%
You have information that you are drawing from a box that contained at least 1 gold ball.
Only 2 boxes contain a gold ball per the problem description.
Thus, the next ball drawn will be the remaining ball from one of those 2 boxes.
The remaining ball can either be silver or gold, per the problem description and information that you have extracted 1 gold ball.
Thus, if you draw another ball from the same box, you have equal chances of drawing a silver or gold ball.

Nope, knowing what could be in the boxes and that you just drew a gold ball rules out the silver-silver box. Only two boxes fit the constraints.
>>677664857
you are wrong because of the greater chance of picking a gold ball from the correct box (2/3). Picking a gold ball from the wrong box is only 1/3.
Probability of next ball being gold is not 1/2, it is 2/3. Faggot.

The probability is NOT how many gold balls there are out of how many balls there are left, it is what is the likelihood the next ball you choose will be a gold ball FROM THE SAME BOX.

INCORRECT!!!! The fact that the first ball drawn from the box was gold, means that you are TWICE AS LIKELY to have picked the ALL GOLD box, thus given the probability of the next ball drawn being gold = 2/3.
See Bertrand's Box Paradox, son:
https://en.wikipedia.org/wiki/Bertrand's_box_paradox
two steps:
First: You know the ball picked is gold, there are 3 gold balls in total, 2 in the first box and 1 in the second box, meaning that there is a 2/3 chance the first box is picked and a 1/3 chance the second box is picked.
Second: if the first box is picked the chance is 100% the other ball is gold, and if the second box is picked the chance is 0% the other ball is gold.
Combining these two gives a probability of 2/3 that the other ball is gold.
p=2/3
Retards
>>677663618
This analysis doesn't work because you assume you can distinguish between the gold balls.
In other words you say you can distinguish between
X,X
X,X
but actually you can't, and this fundamentally matters.
If you don't believe me, read up on the statistics of Quantum Mechanics. Things change drastically whether you have distinguishable and indistinguishable particles.
It's 100%. I'm going to put the gold ball back without letting it go, and take the same ball out of the same box.
Anyone saying 2/3 is a moron. 1/2 is the correct answer. Only two boxes are a possibility. If box is XY then the pull will be Y if the box is XX then the pull will be X. Only two possible outcomes hence 1/2. Any other attempts to explain are plebian and spit in the face of Occam's Razor.
It's 2/3 because it states that the ball you grabbed is gold. There are two boxes in total that contain at least one gold ball. Out of those two boxes there are 3 gold balls and one silver ball. You've already grabbed one of the gold balls so there are now 2 gold balls and one silver, thus the probability of choosing a gold ball would be 2/3.

I will also provide a simple explanation for you idiots. I can't believe someone actually ran a code. What a bunch of losers populate this board jesus.
This question can be asked in this way:
look at the boxes in the pictures.
We randomly choose a gold ball in the picture.
What are chances that the gold ball that we chose is in the left box?
You need to be a retard not to see the answer.
>>677665648
Lemmi esplain.
When you have a gold ball in your hand you could have picked one of three. There is a two out of three probability you picked from the right box, and a one out of three probability you picked from the wrong box.
Even the most certified retard should understand this by now.

Nope dipshit.
The problem statement says you _know_ that you drew a gold ball, not what the probability of drawing a second gold ball after _potentially_ drawing a first gold ball is.
The devil is in the details. OP was trying to be clever, but got the wording wrong.
>>677665189
The probability of the first draw is irrelevent to the probability of the second draw.
Aren't You more likely to take a gold ball from the box that contains 2? Then it's more likely that it is the box that contains the two gold balls?
Holy shit I'm retarded. Been thinking about this forever. It's either 100% or 50% or 0%, depending on which box you take from, now I'm rethinking because that's stupid.
You only have a 50% chance of getting either box with the gold ball in it, and in one box you have 50% chance and other 100% chance, so add them up = 200/300 % chance, which equals 66% chance. I'm retarded
Has anyone heard of Baye's theorem? We have to learn this shit in high school if we have maths, and maths is the most likely subject any random student would have because of the fucking stupid education system.

>>677665930
Check my post below you retard. You're not just analysing the boxes, you're analysing what's inside them. The probability would be 1/2 only if there are EQUAL AMOUNTS OF GOLD AND SILVER BALLS WHEN THE BALLS OF THE TWO BOXES ARE GROUPED TOGETHER. But there aren't equal amounts of the gold and silver balls. YOU HAVE GRABBED ONE GOLD AND NOW THERE ARE 2 GOLD AND ONE SILVER HENCE THE ANSWER IS 2/3

You now have 1 ball in the box.
If you took the ball from the 1st box, you will get a golden ball (success), but if you took it from the 2nd box you will get a silver ball (failure).

Since only two boxes contain gold balls, box 3 is removed from the equation. Easy.
What the 2/3 people people are being hung up on is that one of the gold balls is ALREADY OUT OF THE BOX. Thereby, the remaining balls in each possible box would be 1 gold or 1 silver ball. The probability of drawing that second golden ball is now 50/50.

The probability is either 100% or 0% depending on which box was drawn from. You can't say there is a 50% chance, because if the gold/silver box as taken, there is a 0% chance as the second ball inside will never be gold if the initial ball was gold.

Let me demonstrate how retarded you are with this simple exercise.
I have 2 sweets.
1 is white and 1 is black.
I hide each of them under a cup.
Now I ask you to pick a cup and reveal what color the sweet is.
You pick a cup.
Underneath it is a white sweet.
What is the probablity that the sweet under the other cup is also white?
Now let's word it another way.
You pick a cup.
IF the sweet underneath is a white sweet,
What is the probablity that the sweet under the other cup is also white?
Both of those questions essentially mean the same thing and give the same answer of 0.

This is actually 100% wrong. Grabbing a gold sphere first only eliminates the 3rd box. Theres still 2 boxs remaining, with an equal chance that you could be grabbing from either, which makes it a 50/50 chance. I would say this is obvious bait, but i actually do believe you are this fucking stupid.

Allow me to elaborate. The initial odds are 33% per box because they're three boxes. Picking one does not change the initial odds and your odds are still 33% for picking that one box.
It's not like you can change your choice at that point. You already picked tye box.

There was a 33% chance of choosing the double gold box
And that is what the problem asks
What % chance you picked the box with double gold
Because that's the only way o chose a second gold ball in chosen box
33%
>>677669249
Let's say you select boxes at random, and repeat a large number of times. On average, you will select each box 1/3 of the time. So, 1/3 of the time you will pick the first box (and get a gold ball) and 1/3 of the time you will select the middle box (and get a gold ball half the time, resuling in a 1/6 of the time overall), and 1/3 of the time you will select the third box and get a silver ball. So, given that the ball is gold, it is twice as likely to have come from the first box than the second.
>>677670104
It doesnt matter how many balls exist. What matters is which box you are pulling from. There becomes a 50% chance you are pulling from 2g box, and a 50% chance you are pulling from GS box.

Actually the way the question is written it is a 50% chance. Its only 2/3 IF you ask the question "if you pick a gold ball, whats the chance that the second ball in that same box is also gold." The way its written here, it is already given that you've picked one gold ball and so that first draw does not factor into the probability.
Are they real gold?
>>677670925
I think you should consider redoing that major
2/3
>>677670104
There's only one possible box fucknuts. You can't pull the same ball out and you can't pull from a different box. That leaves two choices. The first choice only matters for the process of elimination. Two boxes left. If box 1was chosen I.e. xx then you must choose x again. If box 2 was chosen I.e. xy then you must choose y. Only two possible outcomes. You are under the assumption that x is distinguishable from x when in fact x is x.

They're most likely gold alloys because pure gold can be bent and dented easily. These images display smooth and dent-less balls, thus they're most likely gold alloys.

Question asks what is the likelihood of chosing the (1) double gold box at the beginning
Because chosing the double gold box is the ONLY WAY to pickup a SECOND gold ball from the box you chose
you have a 33% chance to chose doubl gold box at start right?
So now you are abou to pickup second ball
Well the only way for second ball to be gold is if you had chosen the double gold ball box
Which you had a 33% chance to do
This you STILL only have a 33% chance to pickup that second gold ball
Since it I a 100% chance that IF YOU CHOSE DOUBLE GOLD BOX then your second gold ball will be gold
33% is answer
You all go back to school
>>677671320
This exactly fucking this.
>>677670488
Checked.
The odds are still 33%. Two gold balls are only in one box of the three.
If you were given ANOTHER CHOICE, the odds would change.
You can not choose a different box, so the odds are still the same as the first attempt. Looking at one retrieved ball is a red herring, just a way to prolong the answer.
>>677671113

Another way to represent the problem with cups where you can only take the balls from top
There are 2 possibilities where after first gold the second is gold and 1 where after first gold the second is silver. Again, it's 2 out of 3.
>>677671569
Hi honey bitch face.
You grabbed one gold ball, not two
1/2 I think
>>677671569
That would only make sense if you could change boxes. At this point you already made your choice and odds are still the same
>>677671568
The question is asked after the third box is eliminated. It did not ask what your odds are originally. It asked that knowing you eliminated one box, what are the odds the next ball will be gold. Which is 50%.
>>677670781
It actually did. It asked what are the odds the NEXT ball you grab out of the SAME box is gold. Since you ELIMINATED the SS box, it leaves the GG box and the GS box, which means that its 50%. Read it. It fucking asks what are the odds the NEXT BALL you grab will be gold. That means 1 box is eliminated.
>>677671320

this is so tard it has to be b8. these retards probably go to the casino and lose all their money at the roulette table because they think they know some shit about numbers. the ball is either going to be silver or gold, and neither have higher odds of being picked.. so it's 50/50 u fucking turd. lol

>>677671892
>>677671604
Hes not saying you grabbed 2. Hes saying 1 of 2 possibilities exist. Either you grabbed the ball from GG or the ball from GS. Either way its 50%. There might be a total of 2 gold balls still remaining, but the probability has to do with which box you choose not how many balls exist in those boxs. How many balls exist in those boxs does not effect the likelyhood. You either choose out of box A or box B meaning theres a 50 50 chance.

>>677672748
In the perspective of the 1/2 probability, you would have different probables for each of the two boxes. It asked for the probability of the gold balls within the boxes. It tricks you into considering the boxes by eliminating the 3rd box before you solve the probability. For you just deal with the balls, you'll get 2/3
It's 50%.
You pull a gold out of the box. Meaning it's not the double silver.
This leaves the two possible options that the box you pulled from is either the double gold, or gold/silver.
Because the box can ONLY be one of these two FIXED options, the box paradox logic cannot be applied to this question as it assumes all three remaining balls (2 gold and 1 silver) have equal chance to be collected out of ONE box.
This is not the case however as there are only 2 balls in every box and the one we are selecting only has one in it now. Meaning that if it's the double gold, there is a 100 chance to get another gold. Or if it's the mixed, there will be 0 chance to get another gold.
Basic arithmetic gives the answer. 100+0/2 = 50
>>677672145
The odds don't change if you can't change your choice, faggot.
Originally his odds of choosing two gold balls is 33%. That doesn't change if you know the fucking outcome.

>>677672974
>>677673041
Find fault in my logic without quoting wikipedia.
3 boxs. 1 is eliminated. Whether or not the 2nd ball will be gold depends on which box you picked. 2 boxs. You picked 1. 50/50. Does not matter how many gold balls exist between those 2 boxs. You are still either in box 1 or box 2. Where is the flaw in logic?
>>677671066

>>677673216
It asks what the likelyhood of grabbing a gold ball is AFTER you already eliminate one of the boxs. Its not a trick question.
>>677673293
Yes, they do. Ever watch poker? When cards get shown the chances of a winning hand go up or down based on the new information, even though the hands will not change nor will the card that will be flipped next, its set in stone, but with MORE INFORMATION the statistics change.
>>677672358
>Since you ELIMINATED the SS box, it leaves the GG box and the GS box, which means that its 50%.
That DOES NOT mean it is 50%.
Try to understand it like this:
There are 2 boxes.
1 box has 100 gold balls.
the other box has 99 silver balls and 1 gold ball.
You pick a box at random.
You reach in and take a random ball from the box.
It's a gold ball.
Is it a 50% chance that you have the ball with 99 silver balls?
Think about it.
Answer to OP question is 2/3.
It can be either 1/3 or 1/2 depending which gold ball you chose first.

>>677673301
no, the ball in my example that I took out was a bad example. If u took out of the second box then there is no chance of getting a gold. If you took it out of the first one than you would have 100% of getting the gold ball. Keep in mind it says you take another ball from the same box. I was wrong but I am pretty sure u are also.

If you stop and actually think about it like you aren't stupid, you'll realize that you might as well ask what the odds are of picking a box with two identical balls.

>>677673301
>Does not matter how many gold balls exist between those 2 boxs
Yes it does.
You are twice as likely to have the all gold box by virtue of having piked a gold ball as the first ball.
The fact that your brain can't comprehend this simple fact is amusing.
Look at it this way:
There are 2 boxes.
1 box has 100 gold balls.
the other box has 99 silver balls and 1 gold ball.
You pick a box at random.
You reach in and take a random ball from the box.
It's a gold ball.
Is it a 50% chance that you have the box with 99 silver balls?
>>677673687
much easier
if you switch players after the ball has been taken
how big are his chances to take another gold ball out of that box?
50%
0%
At start you must assume you chose a box that is not GOLD GOLD
Because 2 of 3 boxes are not 2xGold
Then when the SILVER SILVER box is removed we must then assume we chose the Gold Silver box because we ha a 66% chance to chose a non- GG box
Thus, since we assume we chose a non-GG box, and we know that it was not the SS box, we have therefore chosen th Silver Gold Box
0% chance

You are all retarded.
>>677673301
The very fact that the first ball was gold is twice as likely if the box has 2 gold balls. Therefore it is slightly more likely that you picked the right one. Probability is not about intuition, it is solid math, unlike statistics.

https://en.wikipedia.org/wiki/Bertrand's_box_paradox
My first impression was "it's 50%, it has to be because you've already established one ball is gold."
But here's the thing: there are 3 possible situations where the ball is gold: you took the gold ball from the gold/silver box, you took the first gold ball from the gold/gold box, or you took the second gold ball from the gold/gold box.
Pic related, it's a tree diagram that shows all the possible outcomes (given that you don't continue if you pull out a silver ball the first time). As you can see, 1/3 chance of getting a silver ball, 2/3 of getting a gold ball.
I hate statistics but I hate being wrong more.

>possibility 3: a gold ball. Ditto.
So 2/3?
>>677675188
You do not know which box you have chosen. We can only work with what we know.
>>677664418
You start from the situation that you pick a gold ball, from there the chance is 50% for the next to be gold.
>>677676388
At least you took the time to work out the correct answer for yourself, unlike these retarded 50% faggots who insist that they can't be wrong despite all the evidence and solutions showing the correct answer is 2/3.
63.34% And here is why.
You picked a gold ball.
2 in 3 chance you picked box 1 (it has 2 out of 3 total gold balls)
1 in 3 chance you picked box 2 (it has 1 out of 3 total gold balls)
0 in 0 chance you picked box 3 (it has no gold balls)
So 66.67% you got the first box, which is the only box that allows you to get a second gold ball. However, this is where we have to introduce racial considerations. A black nigger will run off with the first gold ball. The only way for the illiterate black nigger to know there was a gold ball in any of the boxes in the first place is if he was told by the owner: a white man, as he has property. It is very unlikely a white man would tell an aids infested illterate black nigger where he stores his gold. This leads me to believe 0% will take another gold ball from the same box.
Less than 5% of the global population falls under the category of aids infested illiterate black gang rapist niggers. Lets assume it is 5%. This means 95% of people will have a 66.67% of getting another gold ball from the same box and 5% of people will have a 0% chance of getting another gold ball from the same box. So on the whole the odds are 63.34%.
Here's the proper mathematical method
P(2 golds | 1 gold) = p(2 golds intersection 1 gold (ie p(2 golds)) /p(1 gold)
= (1/3)/(1/2)
= 2/3
>>677676522
At this point, you must be trolling, as nobody could be this retarded AND double down on it.
Answer is 2/3, simpleton.
Too bad you can't understand it. I suggest you kill yourself as soon as possible to avoid any possibility of spreading the dumb gene.
The answer is: either 100% or 0%.
If you meant to ask, "what is the probability of correctly guessing that the next pull will be a gold ball" then I have to give the same answer (as long as the balls are gold and silver - the metals - and not made of the same material and painted differently).
Gold is heavier than silver. That box will weigh more.

All 50% nigs, listen up :
If the boxes were made so that the first ball you picked from a box was always golden, the prob would be 50%

But my friend, if you read the question Mr MENSA is correct. The first ball is said to be gold, take another look.
Since the first is always gold, you are presented with that 50/50.
I can't believe how much they really believed it was 1/2 despite the evidence.

if i do a coin toss, and i see 19 times tails in a row, whats are the odds that the next one is also tails?
its fucking 50% you fucking highschool dropouts
>what is statistical independence
>>677677804
if you got the gold one first, that means that it is either the gold/gold box or the gold/notgold box. hence the chances are 50/50
The question asks what is the likelyhood to chosing a second gold ball
There is only 1 box out of 3 that makes this possible
Thus you have a 33% chance of chosing the box with GOLD GOLD
So the only way for you to pickup two GOLD balls in a row is if you hit on your 33% chance to chose the GOLD GOLD box
When you make your first choice you set in stone your % chance of having the ability to chose double GOLD
Removing the SILVER SILVER box dose not change the fact that you had a 33% chance to chose the GOLD GOLD box
You still have the same box that you did before the SILVER SILVER box was removed
So you still hav a 33% chance to draw a second GOLD ball after drawing the first
>>677678348
The first isn't always gold. The first one you grabbed was gold. You didn't grab one gold from each of the boxes. You grabbed one gold from one of the two boxes, thus leaving you with one silver and two gold balls.
I've posted on here about 20 times.
The probability of you grabbing a gold ball is 2/3.
>>677678348
The first is always gold, so that means you picked box 1 or 2. It is however more likely you picked box 1, because it has two gold balls. The odds you picked box 1 are infact 66.67%.

You have a 2/3 chance to chose a box that gives the opportunity to chose GOL as the second ball in the box
The GG & GS
An once the SS box has been removed, and since you have chosen a GOLD first ball, your second GOLD ball can not possibly come from the GS box
Thus you have chosen the box with GG and have a 100% chance to chose a second GOLD ball
>>677679289
it's given that the first pick is gold. That has absolutely no bearing on the probability of gold in pick 2. This is a memoryless problem

i'm steven hawking, actually its 25% you peasant
2/3. The GG box has two possibilities, since either gold ball could've been chosen first. This means of the 3 possibilities , 2 of those are pulling another gold meaning the chance of another gold is 2/3.

AWESOME REPLY ILY

NOT AMERICAN HERE
The answer is 2/3
>>677679388
cool story the text in the OP is still incomplete
should have taken reading comprehension classes instead you fucking faggot
it does not say whether he removes the coins/boxes from the pool or puts them back in again after picking
>>677678675
If I give you a box that contains 2 gold balls and a box that contains 1 gold ball and 1 silver and tell you to pick from either box at random, which box is more likely to give you a gold ball?
Hint: It's box 1. Box 1 is more likely to have given you a gold ball, because it has twice as many gold balls.
Therefore, if you pick at random and retrieve a gold ball, it is more likely that the gold ball came from the box with 2 gold balls. See how that works? See how fucking simple that is?
Since it is more likely the ball came from the box with 2 gold balls, it isn't a fucking 50-50 chance you picked from either box. In fact, it's a 66% chance you picked from the box with 2 gold balls, because 2 of the 3 total gold balls are in the box with 2 gold balls.
The events aren't independent.
The boxes are not equal.
Your inability to see that is a sign of crippling autism.
>all these retards unable to do maths
13/24, just over 1 half/50%
33% chance of selecting 2 gold box = 1/3
75% chance of select gold from boxes not all silver = 3/4
1/3 x 4 = 4/12
3/4 x 3 = 9/12
4/12 x 9/12 = 13/24 chances
idiots

I'm Einstein, (ps I made myself immortal)
the answer is clearly pi times radius of my personal circle's arc centre perimeter is equal to 360 X gravitational waves = 48%
100%
One of the boxes has no silver balls so we can rule that one out
Two of the boxes have a gold ball in them and between those two boxes there are 4 balls 3 gold and one silver
Since you have one of the gold balls you might think the next one you take has a 2/3 chance.
But you are wrong it say you take a gold ball and only one box has 2 gold balls 1/1 100%

This isn't bertrand's box
Bertrand's box says
>What is the probability of taking a gold, then taking another gold
the proposed question is
>given the first was gold, what is the probability that the second is gold
See the difference? yes, the subtle difference in wording matters
>>677679603
>That has absolutely no bearing on the probability of gold in pick 2. This is a memoryless problem
there are 2 boxes
1 box has 100 gold balls
the other box has 99 silver balls and 1 gold ball
You pick a box at random.
You pick a ball at random.
It's a gold ball.
What is the probability that the next ball you pick is also gold?
Still think it has no bearing?
Answer to OP is 2/3

1.) Weigh the two boxes you didn't pick from. The lighter one contains two silver balls.
2.) Weigh the box you're picking from. Double it.
That information will allow you to correctly predict the probability.
The answer will be either 100% or 0%.
I actually can't believe that the majority of you are 18+, some with math majors and still can't figure out this probability question.
2/3 / 66% ride or die
btw you die if your retarded brains worked out 1/2 / 50%, 1/3 / 33%, and anything in between
>>677679597
Exacally someone gets it
>>677662400
50% you fucking retards. Theres a 50% chance that itll be gold, and there is a 50% chance itll be silver.
>>677680137
this is still 50% on the second ball.
you're not asking the probability of picking a golden ball then a golden ball, you're asking the probability of picking a golden ball after knowing your first ball was gold.
learn to math, and learn to English you fucking pleb
>>677680135
Now you're making shit up to make yourself appear less retarded.
Unfortunately for you, we can read the article about Bertrand's Box Paradox ourselves without having to rely on your lies.
OP's question is a version of the Bertrand Box Paradox.
the answer = 2/3.

>>677680689
You're a pure retard.
I'm 18- and I was capable of working this out correctly.
Learn why the answer is 2/3.
Don't deny it, learn it and build your knowledge.
Someone reference the success ice burg.
not even MOOCs can save us from global stupidity
>>677680719
>you're asking the probability of picking a golden ball after knowing your first ball was gold.
Exactly. That's why the answer is 2/3, you simpleton.
If you didn't know the first ball was gold, then then the probability of getting 2 gold balls in a row would be 1/3.
But we KNOW the first ball was gold.
There are 3 ways to get a gold ball as the first ball.
2 out of those 3 ways gives a seconds gold ball.
1 out of those 3 ways gives a silver ball as the second ball.
Answer = 2/3

I know what Bertrand's box is. The proposed question is not the bertrand's box paradox.
>itt: OP uses subtle shift in wording to troll the fuck out of people who know math but can't read to save their life
>>677662400
33 god damn percent, there is a 1in 3 chance you picked the double gold ball box
Shout out to all my 2/3 homies who stuck to their 2/3 answer right at the very start despite the over flow of retards and autists almost causing us brain damage with their 1/2 answer floods.

Yes it is. Read it and weep.
https://en.wikipedia.org/wiki/Bertrand's_box_paradox
Answer = 2/3
you have a 66% chance to pick a box which has at least one gold ball
Thus allowing your second picked ball to be GOLD
You obviously hit on this chance by chosing one of the boxes that let you chose your first GOLD ball
And since you did hit a box that lets you chose a GOLD ball second, and your first choice was a GOLD ball, you must have chosen the GG box since the GS box gives 0% chance to chose a gold ball after having chosen a GOLD ball first
Thus you have chosen the GG box and you have a 100% chance to NO chose a second gold ball
