Menu: [Distribution]-[Hypergeometric PD]

Description: This command calculates the probability the random variable that follows a hypergeometric distribution will be a given x value.

prob = MCx ×N–MCn–x NCn

Definition of Terms

x : specified trial (integer)

n : number of trials from population (0 < n integer)

M : number of successes in population (0 < M integer)

N : population size (n < N, M < N integer)

Calculation Result Output

prob : hypergeometric probability
