An Urn has 10 good balls, and 70 bad balls. 20 balls are drawn at random. What are the odds that exactly 6 of them are good?
The above question is a classic Urn problem, which can be solved via the hypergeometric distribution function. It's a short piece of Mathematica code. An analysis of the fairness of various gambling games (poker, keno, bingo, and the lottery) is given.
