This should be easy

Can you please show work before thread dies

2/3, you know you don't have the third box as soon as you get a gold coin.

1/9

I've done this thread before, but because the problem is kinda old, its not that well known outside of math classes on conditional probability, but just an hour ago a video was posted that explains it very well.

So i will post a link to it a little later.

50% likelihood it's gold

2/3 because there's 2 gold balls and one silver remaining after excluding the silver silver box

They are right and you suck.

You have box A or box B, so changes that you pick a second gold ball is 50%
Now if we did not know the first ball and your question was how big the changes are of picking two gold balls, the answer would be 25%

That would only be right if all balls were in one box, which they are not.

they are wrong and you suck.
you have no idea what you are talking about but you still act like you do.
i KNOW the answer, i know every aspect of it, even the name of the person that came up with it and when he came up with it.

I will post evidence a little later.

60% chance you get a silver ball

If you picked a gold ball, that means it's twice as likely your hand is in box 1 than in box 2.

Therefore 2:1 odds you pick another gold, or 66%.

(since the only possibilities are hand in box 1, or hand in box 2)

You are wrong and you suck. Prove me wrong.

3.14

i will, but the thread is still young, i dont want to spoil it right away.

in 10 minutes i will post it.

You can use that time to figure out why you are wrong.

67%

Too late! already solved:

2/3

There are 3 gold balls, you have grabbed 1.
A) 1/3 chance you picked ball 1 from box 1
B) 1/3 chance you picked ball 2 from box 1
C) 1/3 chance you picked the gold ball from box 2

A and B both give another gold ball, C does not. So 1/3 + 1/3 = 2/3.

thats very close but not quite.

oh i know people have posted the right answer, but these idiots wont believe it untill they see evidence, cant fix stupid you know.

Oh, I know.

At first there's a 66% chance that you will pick a box with a gold ball. Then it's a 75% chance that you will pick a gold ball out of those. 0.65 * 0.75 = 49,5% chance.
Since you've picked a ball already there's 3 possible balls left to pick. 49.5 / 3 = 16.5% to chance pick a silver ball. That leaves 33% chance left.

Thus, 33%

69%

>there are 3 balls still left that can be picked
>2 of them are gold
> 1/3 chance for gold
wtf have you been smoking?

2/3

wow im smart 3301 sign me up

But there's only 16.5% chance of being a silver.

You are an idiot. The question is not ‘what are the odds to pick a box with 2 golden balls’, but ‘you have a golden ball, what are the odds that the next ball is a golden one aswell’.

The third choice is out of the picture because you know that one of the balls is golden. Therefore it is either box 1 or 2 - 50%

that part is also wrong.

Ok 10 minutes passed, here is the video
youtube.com/watch?v=ytfCdqWhmdg
its at 9:30 but you should watch the whole thing.

50% you utter retarded faggots.
you already have 1 gold ball. so that leaves a gold ball (your hand is in box 1) or a silver ball (your hand is in box 2).

The premise in the video is different to the picture. If you put the golden ball back into the box, then the probability in the video would be correct, but there’s no mentioning of that.

I could add scenarios like the odds of being killed before he manages to pick the ball and disprove his calculation, too. It is just deceiving and plainly stupid

100% left box. 0% middle box.

It doesn’t. That’s not how it works at all. The odds of what box you picked first are meaningless to the fact that there are only 2 possible outcomes, gold from 1 or silver from 2.

well ur not any better

don't bother with this. Answer is 50% probability, tho OP tries desperately to convince himself it's 66%.

the chances to pick a box with a golden ball at first is 2/3 for box 1 and 1/3 for box 2, because in box 1 are double the amount of golden than in box 2.
this has not been asked in the question at the beginning.
if there has already been a ball pulled out and it is clear you're whether in box 1 or box 2, the odds for another golden ball is 100% for box 1 and 0% for box 2. because the first golden ball has already been chosen and is out of the game, there isnt another possibility in box 1 to change golden ball and add up %.

50% for another golden ball if you've already pulled a golden ball and 2/3 if you stand in front of 2 boxes, one with 2 and one with 1 golden ball.

no

this

kids learned about bertrand’s box and spread their bullshit everywhere

to simplify it for the biggest brainlets here: imagine russian roulette without spinning the chamber.
there is 1 bullet inside.
your chamber got space for 6 bullets
the last 5 shoots were empty

realistically, the sixth shot is 100% going to have the bullet inside but under their brainlet logic, the probability is still 1/6

OK... This one is with all of my might. By the power of Kek, GRANT ME THIS POWER!!

damn how sad is your life?

Correct. They try to use the coins to show 2/3, when in reality it's the boxes that matter. Once you've pulled a gold coin, you're left with only two boxes as options.

The number of coins only comes into play for the first pick, which is also 50/50, but it's irrelevant since we've started with a 100% chance of a first pulled gold.

Ha, you think it's samefag?

so basically op or is a nigger faggot for not being clear enough

>Can't even get pity dubs on farewells
off to kms

If you picked a box at random and it has a gold ball, then you can rule out the box with only silver. You thus have a 50% chance of getting a gold ball because either the second ball is from the all gold box or its the from the half gold box.

this one got the answer

1/3

A G A I N

50/50
if you pull a silver ball, you know it ain't the box with 2 gold balls
if you pull a gold ball, you know it ain't the box with 2 silver balls
balls. uh huh huh huh....balls. he said balls
