    Eighty percent of the employees at Rowan University have their biweekly Wages deposit directly to their bank by electronic deposit program. Suppose we select a random samples of 8 employees. What is the probability that three of the eight (8) sampled employees use direct deposit program?

    Use the binomial distribution
    • p = 0.8
    • n = 8
    • k = 3

    So we want P(X = 3)
    Using our binomial distribution calculator, we get P(X = 3) = 0.0092
