Fuck you

2/3, this is just the Monty Hall problem

Why are you asking me?

50%

1/2 because once you chose a box you have no access to the other two, limiting your possible outcome to ONLY the other ball in the box. either you chose the box with the 2 gold balls or the one with only one gold ball. Two possible outcomes are left: pull the second gold ball or pull the remaining silver ball

2/5ths

There's 5 balls in total, and 2 of them are gold.

it's 50%

bait

>>719200306
1/2

Any other answer is bait or retarded

>>719200306
50%, you're in either the 2 gold box or the 1/1 box.

9/11 never regret
2 EZ, OP=bait

>>719201878
you're the bait

since you grabbed a gold ball, the chance that you did so from the 2 gold ball box is 2/3. Therefore the probability that the next one is gold is also 2/3.

Engineered.

>>719202297
no

>>719202297
>the chance that you did so from the 2 gold ball box is 2/3
Where the fuck did that come from?

>>719202297
why would the chance of you doing so the first time be 2/3, it's 50/50

50:50

>>719202120
duh

So it's your first year at university right?

baited like true bait

>>719202297
wrong it's 666/999 because fuck you

Hillary Clinton is a lizard

also 0.5

First selection you have 50% of choosing a gold ball

Second selection, given you already selected a gold, you still got 50% motherfuckers

Bayes up in dat ass

Let's iterate through. We already cut off the double silver box since it can't meet our requirement of drawing a gold ball.

Gold 1
Gold 2
Gold 3
Silver 1

If g1 is drawn, the partner is g2. Success
If g2 is drawn, the partner is g1. Success
If g3 is drawn, the partner is s1. Failure
S1 cannot be drawn for the test to work.

So our chance is 2/3 or 66.66%

I work at White Castle LOL

the fact of the matter is that your all grabbing balls..... pretty gay isnt it

0.5

Ambiguous question. The probability you will pick two gold in a row or the probability once you have removed on ball?

The chance you grabbed a gold ball is 1, because it stated that you did. Therefore it's simply whether you pulled from the double gold or the mixed box.

Damn, I thought it was 1/2 but Wikipedia says 2/3:
https://en.wikipedia.org/wiki/Bertrand's_box_paradox#Solution

>It may seem that the probability that the remaining coin is gold is
1/2, but in truth, the probability is actually 2/3. If a gold coin was withdrawn in the first step, it is more likely that this happens because the chosen box is number 1 (the box with two gold coins) than box number 3 (the box with one coin of each type).

>>719203400
(You)

50/50, either you will get a second gold ball, or you won't.

This can be applied to most things. For example, you roll a d6 5 times, what is the probability of it landing on 6 each time? 50/50, either it will or it won't.

maths teacher here
The answer is 50%
since gold was the colour of the ball first pulled out , the only two boxes to consider are
1.GOLD GOLD
2.GOLD SILVER
Therefore if its box 1, the next will be gold
if box 2, the next will be silver
therefore only two possible answers where one is successful, hence 1/2 = 50%

Kek

>>719203956
But there are two instances of being able to pull from box 1 while only 1 instance of pulling from box 2

>>719200306
This is so obvious. 1/2 and anyone who says otherwise is a dumb nigger

>>719202297
Wrong

>>719203862
now you're just trolling. But for the balls it is 50/50 tho

>>719205476
Not trolling, every chance is 50/50, yes or no, quite simple.

I am a professor of ball and box probability at a very advanced Ivy League School. It is obviously 1/2

>>719204429
you know you already have a gold ball, so what is the likelihood that you will get another one? since the two gold balls in the first box are identical for the purpose of this test, they will be considered the same

you either picked the double gold box or didn't, 50/50

>>719203159
you're not picking balls you're picking boxes. no wonder you work at white castle

Im taking the bait

The first chance is 50/50 because 3 golds, 3 silvers.
What its asking is the NEXT drawing's probability.
>Remove one gold: 2 golds left, 3 silver
2/5.

2/3 is correct, because you have 3 golden balls. If you pulled one of the two of the first box, you get another one. These are 2 of the 3. so: 2/3

>>719206752
>you know you already have a gold ball
what's the chance that the gold ball you already had was from box 1, considering there's 2 gold balls in box 1 and only 1 in box 2?

2 + 1 gold balls ( = 3 lul)
2 in box 1
2/3 chance your first ball was from box 1.
Q.E.fucking.D.

if you're too dumb to google "monty hall problem" in 2017 then there's not much that can be done for you.

>>719200306
it's been many moons since I've seen this bait.

protip: your hand is twice as likely to be in the double gold box. Its almost like if you're forced to have a gold ball in your hand, its 2/3 chance to be from the box on the far left.

do you fucking niggers even into laplace

>>719200306
The only right awnser is 50/50

You already have a gold ball, so your next ball is either silver or gold. Since you don't know which box holds which balls, you have a 50/50 chance your next ball is golden.

>>719200306
3 scenarios
>gold ball in hand, other ball in box is gold
>gold ball in hand, other ball in box is gold
>gold ball in hand, other ball in box is silver

hmmmm 2 of those scenarios out of the 3 leave you with a gold ball in the box.

>inb4 stupid fags try to convince you to collapse the first two scenarios into one

thats fine, as long as you add their probabilities together :^)

>>719201806
Keep wanting, anon

I think I get the confusion, can people confirm this? The answer is 66% because of >>719208885

>What is the probability that the next ball you take
is inequal to
>What is the probability that your box is the correct box

And a lot of people are answering the second question, which is 50% because there are only two possible boxes, but we're comparing three balls; not two boxes.

Is that right?

>>719208885
you're counting the first box twice

>>719209526
if at the start of the problem I have a gold ball in my hand, its one of those 3 balls right?

>>719209446
"Is your box the correct box" can't be answered without additional information (ie the answering strategy) so, no, you have misunderstood. But the other answer is 2/3.

>>719209802
Okay, thanks, I'm still trying

>>719209797
yes, but you shouldn't count 1 box twice
