Hypergeometric Distribution

JavaScript

---

From a population of size N, containing a subpopulation of size m, a sample of size n is drawn at random without replacement. The number, X, of the sample that were drawn from the subpopulation is said to have a Hypergeometric distribution, H(N,m,n).

      Enter the population sizes, the sample size and the cutoff point.

       Population size N: 
    Subpopulation size m: 
           Sample size n: 
                 x-value: 

P(X <= x|N,m,n) :

The exact probability is calculated. For example, P( X<= 75|1600,400,300) = .53252.
Computation time is proportional to x+min(m,n,N-m,N-n).
