Description
The vRngHypergeometric function generates hypergeometrically distributed random values with lot size l, size of sampling s, and number of marked elements in the lot m, where l, m, s∈N∪{0}; l≥ max(s, m).
Consider a lot of l elements comprising m "marked" and l-m "unmarked" elements. A trial sampling without replacement of exactly s elements from this lot helps to define the hypergeometric distribution, which is the probability that the group of s elements contains exactly k marked elements.
The probability distribution is given by:)

, k∈ {max(0, s + m - l), ..., min(s, m)}
The cumulative distribution function is as follows:
