    There are 24 blue marbles of 100. What is the probability of drawing 25 blue marbles out of 60 tries? I believe the answer should be .0011. I am blanking on how to actually get to this. There is replacement after each pull.

    Sorry no stakes. Do it out of the kindness of your cold black heart.

    This is easy! There is a 0% chance of drawing 25 blue marbles out of 60 tries when there are 24 blue marbles out of 100.

    Easy game

    it's <span>(60! / (25! * 35!)) * ((.24 ** 25) * (.76 ** 35))</span>

    Maybe it still wasn't obvious to him. Hopefully my answer above shed a little more light on it. To elaborate for OP just a bit more, you need to find the number of ways to get exactly 25 blue marbles out of 60 "pulls", which is C(60, 25) [http://en.wikipedia.org/wiki/Combination]. Then you need to multiply that by the probability which is the (.24 ^ 25) * (.76 ^ 35) bit -- 24/100 * 24/100 * 24/100 and so forth for 25 marbles, then 76% probability for the remaining 35 "pulls".
