You have a jar that is filled with a hundred marbles, each of them either black or white, but you have no idea how many of each color there are. However, you have been told that all possible quantities of white marbles (from 0 to 100, both inclusive) are equally probable.
You randomly select 100 marbles from the jar one at a time, with replacement, and they are all white. What is the probability that the jar contains only white marbles?
Following up on my previous post, it seems the answer to the 100 marble case is:
(100^100) / [sigma (x: 1 to 100) x^100]
I'm not sure how this can be simplified, and I get the feeling it's incorrect ... but that's what I got.
