MathCumulativeDistributionHypergeometric

Calculates the value of the probability distribution function for hypergeometric law with the m, k and n parameters for a random variable x. In case of error it returns NaN.

Parameters

x

[in]  Value of random variable.

x[]

[in]  Array with the values of random variable.

m

[in]  Total number of objects (integer).

k

[in]  Number of objects with the desired characteristic (integer).

n
