— Function File: hypergeometric_cdf (x, m, t, n)

Compute the cumulative distribution function (CDF) at x of the hypergeometric distribution with parameters m, t, and n. This is the probability of obtaining not more than x marked items when randomly drawing a sample of size n without replacement from a population of total size t containing m marked items.

The parameters m, t, and n must positive integers with m and n not greater than t.
