Question: When calculating all the values of a hypergeometric distribution the
When calculating all the values of a hypergeometric distribution, the work can often be simplified by first calculating h(0; n, N, M) and then using the recursion formula
Verify this formula and use it to calculate the values of the hypergeometric distribution with n = 4, N = 9, and M = 5.
