Default Re: Extremely Difficult Probability Problem

[ QUOTE ]
you can get the same result by thinking of the question as being "what is the probability that a fair coin comes up the same all 10 times it is flipped" (i.e. all the marbles are the same color) which is (1/2)^10 or 1/1024

no, this is the probability before you do any of the removal of marbles and checking that they are white. after you've sampled 10 times and seen 10 whites, the probability is different.
