Possibility 1: You pick one gold ball from first bag, the next ball WILL be gold

Possibility 2: You pick the other gold ball from bag one, next ball WILL be gold.

Possibility 3: You pick the gold ball that's with the grey ball, it will NOT be gold.

2 out of the 3 possibilities end in you picking a second gold ball. The third bag isn't part of the probability because it's impossible when you assume the first ball you pick is gold.

2/3 chance is the answer.

right but there's only a 1/3 chance you picked the gold ball from box #2, but a 2/3 chance you picked a gold ball from box #1. Therefore, you have a 1/3 chance of not drawing a gold ball (box #2), but a 2/3 chance of drawing the other gold ball from box #1.

>>677846751

No. S/He's not. Each draw is a different roll. We know that the first ball was gold, that eliminates the two silver box. So the real question is, what are the chances you have the box with two gold balls of the two possible choices. The chance of that is 50%. Suck my dick, any statistics or math fags. These are facts with simple math, simple always trumps abstract.
>>
>>677846950
But what if he pulled it from the one with two silvers? Then it's 0% chance.
>>
>>677847453
wrong
>>
>>677847453
It's a box pick and not a ball pick so ball 1&2 from box 1 counts only as 1 pick
>>
You have 3 boxes, in the first stage you have 1/3 chance for any of the boxes.
Once you remove your first ball, and you see it is gold, you know for sure your next ball is going to be either silver, or gold.
Since the first ball is already a known fact, you only have to calculate what your chance is on finding the NEXT gold ball: 50%

TL;DR: I'm a math-fag and i just explained why it is 50%
>>
>>677847746
Good explanation you cuck
>>
>>677847453
50%chance that the box you randomly picked is the one with 2 gols balls - no matter which one of them.

50% chance you picked the box with 1 gold and 1 silver - next ball will be silver.

Godfuckingdammit its not that hard stop trying to make up shit.

>>677846669

the question is about the probability that the next ball you take from THE SAME box will be also gold.

They're all just going to stick with it being a box picking problem when it's actually a ball picking problem. They're so focused on the boxes that they aren't noticing that there are THREE gold balls. Picking one gold ball over the other in box one ARE two different outcomes.

The probability that GG would produce a gold coin is 1.

The probability that SS would produce a gold coin is 0.

The probability that GS would produce a gold coin is 1⁄2


Originally, all six coins were equally likely to be chosen.

The chosen coin cannot be from drawer S of box GS, or from either drawer of box SS.

So it must come from the G drawer of box GS, or either drawer of box GG.

The three remaining possibilities are equally likely, so the probability that the drawer is from box GG is 2⁄3.

1/2 probability, the question is of the probability AFTER already finding 1 gold ball, cutting off the box with the silvers, meaning all you have is the probability of 1 box vs 1 box
>>
2/3 chance to pick a box with gold in it and 1/3 chance to pick the box with two golds in it

So if middle box is picked first it will be 1/3 chance to get first box.
Answer equals 1/3

If first box is chosen first it will be a 2/3 chance to get a box with a gold ball in it but a 1/2 chance to choose gold on the second box.

1/2 * 2/3 = 1/3

Final answer is 1/3

there's 3 gold balls and one silver.

Eliminate one gold and you're left with 2:1 gold to silver. That's a probability if 67% you'll draw another gold ball now. Just because you pick a box doesn't matter. The balls could be in the same box and the odds remain the same.

Good reader.
>>
>>677848786
the actual question states you know for a fact you have a gold ball, you are only trying to find the probability of the next ball in YOUR gold box.

there could be 1 million Silver Silver ball boxes before the question, the answer is still 50%
>>
>>677849451
That would be true if you also hadn't picked a gold ball as well
>>
Here's the one true answer:
Before picking up one ball there is a 1/3 chance, because only one box has 2 gold balls.
After picking up a gold ball there is 1/2 chance because one of the two boxes that has a gold ball has 2 gold balls.

No, if you consider the theory Schroedinger's cat (Which I am basing it loosely and don't know the actual theory so fuck you if I get it wrong) you would not know which gold ball from GG has been picked and it is equally likely of it being both so we can imagine it as a state the they have both been picked and regardless of what happens, from GG there will always be another gold to pick.
>>
Gold privilege is giving the first box TWO chances
>>
>>677848848
You're ignoring the wording of the OP.

The odds that the second ball you pull will be gold, as the first ball is removed from the equation entirely. Since the first ball only seeks to determine that you have chosen either box one or two, it's irrelevant, so treat the boxes as though they contain one ball, gold, or silver. One, or the other. 50:50, if you will.

It's quite simple actually.
You have already picked the gold ball... that means that you got the box number one or two, that being said it, pretty much dismisses the box with 2 silvers.
You have to look at it from the perspective of the boxes, not balls, you already know, that you picked one of the first two, so there are only 2 possible outcomes
There is actually a term in mathematics for something like that... but I am not a native english speaker, so I don't know it... instead of dividing the number of desired outcomes by the number of all possible outcomes, u divide it by the number of outcomes that match the given condition (getting one gold ball first)
calculating probability like that goes like this
P(getting gold after already getting gold - desired outcome on the condition that we already got a box with gold)=P(picking the box with 2 gold - desired outcome)/P(picking the box with at least one gold - condition)=(1/3)/(2/3)=1/2=50%
>>
>>677846669
the way I see it:
we know first draw is a gold ball so we either drew from box one or box two
let's assume the balls aren't put back into the boxes after the draw, that means we either have 100% chance to draw another gold ball from box one or 0% chance to draw another gold ball from box two, which means we have 50% chance total to draw another gold ball

if we assume the balls are put back however, we have 100% chance to get another gold ball from box one and 50% chance to get another one from box two, which makes it 75% this time
>>
Literally the only way this could be different from 50% is if you are putting the ball back in the box. That increases the odds to 75%.
>>
>>677850677
there are two possible outcomes, but not equally likely. if you picked a gold ball, then you know you either have box #1 or box #2. but not with a 50/50 chance. you have a 2/3 chance that you have box #1, and only a 1/3 chance of having box #2.

since you got a gold ball, you're in one of the two left boxes.
1/3 chance of being in the mixed box, 2/3 the double gold box. Aka. 1/3 of the time it's 0% that the other ball is gold, and 2/3 the chance is 100%. Multiply probabilities ==> answer is 2/3.
>>
>>677846669
GG
GS
SS

You picked a gold ball. Your box therefore is either:

GG
GS

What is the probability the other ball - in the same box you just picked from - is gold as well?

50%.

G[G]
OR
G[S]

We know SS is impossible, therefore we must draw our probability from this new matrix of boxes.

Anyone who disagrees is either trolling or just plain dumb.

Except the wiki link clearly describes the same exact conditions save balls being coins instead.

Maybe this way of thinking will help you:

If you pick a gold ball from a box you have 2 gold balls and one silver ball existing.

GG
GS

As you can see if you remove the G from one of those.

Think of this as well, you can pick a gold balls from GG in two different outcomes, and GS once.

If you pick from GG, the probability of the next ball being G is 1. If you pick from GS, then the probability is 0. This is what may lead you to think it's 1/2. But you are forgetting one thing, you can pick a gold ball from GG in TWO different outcomes.

GG
GG
GS

When you pick a ball, one of those outcomes becomes reality.

You are twice as likely to pick the box with two gold balls then you are to pick GS given this scenario.

You can consider them as the same fucking ball. Also It is asking about boxes not balls. There is two boxes that can be picked
[G]
or
[S]
If you pick G, you will get G as the second ball
If you pick S, you will get S as the silver ball.

>>677846669
It's very simple.
It appears to be as if you're picking from box 1 or 2, but you're not.
It's stated that you pick a golden ball, so you have to look at the probability of picking a box where you pick a golden ball which would produce another golden ball.

3 golden balls, 2 of them will produce another golden ball if you pick it.

Answer is 2/3. Don't dismiss the probability of you picking a silver ball if you first stick your hand in box number two.

This has nothing to do with quantum mechanics you idiot.

>>677853531
there are 3 possibilities :

1) you picked the 1st gold ball of the gold bag and will then pick the 2nd gold ball in it
2) you picked the 2nd gold ball of the gold bag and will then pick the 1st gold ball in it (different situations, get it?)
3) you picked the gold ball from the other box and will then pick a silver ball next

there are 2/3 favorable ways for getting a gold ball again then the probability is 2/3 now gtfo

when you first put your hand in to grab it would be 50/50 but since 'devine intervention' steps in you get a gold ball.

so now the odds are no longer 3:3 gold ball but 2:3 that you'll get another gold ball. RIGHT?

WRONG NIGGA

Because the boxes with gold balls either have 1 gold ball or 2 gold balls. so the box with 2 silver balls is disqualified INSTANTLY. RED MAGIKARP!

Okay, so it's either silver, or gold. but the chances you grab a box with a gold ball in it is 2 times more likely to be 2 gold balls box, then 1 gold ball box. since it's "RANDOM".

So, with that in mind, if you did it randomly 3 times with every possible outcome, you'd have 2 gold ball box, 2 gold ball box, 1 gold ball box.
So the answer is still the same as the start.

2:3=2/3=66.6/100 it's another gold ball.

Further elaborating, you can pick GG twice and GS once. Your flaw in thinking is that there is only one GG outcome when there is two.
>>
>>677854838
either of the 2 gold balls in GG box. plus the GS, 3 outcomes, 2 with another gold, 1 with SILVER LOSER BALL FOR FAGGOTS I FUCKING HATE SILVER.
>>
I think it depends if you are asking what would be the probability, starting from the point where you are picking the box, or what is the probability from after you already drew the gold ball.

For example, I flipped a coin and got heads twice in a row. What are the odds the next flip will be heads? Well if you giving the odds of getting 3 heads in a row, the answer is 12.5%. But the way the question is worded, it's asking about the next flip, which of course would be 50%.

it actually plays with multiple sets of probability, and even one set of non-probability (certainty?) and then a box of 2 silver balls for no reason.

>>677855407
it's ment to be tricky, so I don't agree, I think a lot of people would be stumped by this. probability is quantum level ideas. in all reality probability is highly valued idea. to say africans are REALLY good at probability is to say all black people are as intelligent as Data from star trek.

My thoughts exactly on you. Do you know the that with statistics and probability you can predict anything in the world, and thus predict the future, to the point of even changing future outcomes and even causing people to commit suicide.

complex probability is why people think you can't predict the future, even though WE CAN. This is a simple example of that, but do you know the answer? is it 50/50 or 2/3? hint: it's the same as what you would guess in the start!

I was thinking that the fact that you chose a gold ball might affect th probability so it's not 50%, but if you chose a silver ball first, the odds of picking a gold ball would still be the same in this scenario.

If you're not a moron, 100% or 0%

Gold and silver are different densities. The three boxes will weigh different amounts. And you can easily pick the heaviest and lightest boxes.

you're given that you choose a box containing a gold ball (50% chance)

multiply that by the chance of picking another gold ball (2/3 or 66%)

50% x 66% = 33% or 1/3
>>
2/3s Call me stupid all you want, this is how it is.
two boxes have a chance of you picking gold, there are three boxes. And the retards saying one thirds, fucking kill yourself. 50% people. I can understand where you're coming from.
>>
>>677857068
right answer, WRONG REASON, it's actually because there are 3 gold balls and 1 silver ball, and you have one of the gold balls.

not given the choice of choice, you get a box with a gold ball in it to start.
