How good is Yas Forums at maths/logic?

33.3% you'd have to pick the box with 2 green balls to get 2 green balls. So you'd only have a 33.3% chance from the start.

EITHER I GET MILLIONAIRE TODAY OR I DON'T. is it 50%?

I've got an advanced mathematics degree but I'm also stoned so who knows

The green ball is already selected, if from Box A then P of 1.0; if from Box B then P of 0, the green ball can not have been selected from Box C.

Therefore, you have P of 0.5 that the other ball in the box is also green.

Do you guys have good books or something to improve my maths logic and maths level please ?
I feel like my brain is empty or numb doing this shit

The probability depends on which box you picked it from. The left most 100%, the middle 0%. Idk maybe i'm retarded.

If the first ball was green, that double red box is automatically irrelevant. So it's a 50/50 shot the next ball is either green or red.

if a green ball has been selected, these are the possible outcomes

Because you're all racists who need more multicultural influence so I put more green balls in all the boxes while OP wasn't looking.
