You can put this solution on YOUR website! A hypergeometric probability distribution is used when the probability of a success changes on every trial.
:
The parameters from this problem are,
:
N = 15, The number of tax returns in the population
k = 9, The number of tax returns to be audited(successes)
n = 3, The number of tax returns in the sample
x = ?, The number of tax returns in the sample that reported losses(successes)
