Question 1106611: I don't know if I'm in the right section or anything, but just need to know the steps and answer to this simple chance experiment:
I have a jar of 60 marbles. 58 are blue and 2 are red. If I draw out a marble 15 times without putting any back, what is the chance I draw both red marbles?
Thank you very much in advance! Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Chance don't draw either is 58/60*57/59*56/58*...*44/46=0.5593
That is the brute force method.
for 0 is 58C15/60C15, or 0.5593
for 1 is 0.3813, 58C14*2C1/60C15
for both is 58C13*2C2 (which is 1)/60C15, or 0.0593 answer.
