Hi,

Someone posted this Hypergeometric Distribution formula
C(D,k)*C(N-D, n-k) / C(N,n)

and a wikipedia link but that link didn't answer this questio:, what is the

C(N,n) represents the number of combinations of N things taken n at a time.

C(N,n) = N! / ( (N-n)! x n! ) where ! = factorial n! = n x (n-1) x (n-2)
x ... x 1.
Also 0!=1
