    Solution Preview

    This is binomial distribution
    p= probability that employee call in sick= 60%
    q=1-p= probability that employee does not call in sick= 40%

    A) exactly three employees will call in sick

    Probability = (10 C 3)* p^3 q ^7=

    (10 C 3)= 120
    p^3= =60%^3
    q^7= =40%^7

    Thus
    Probability = (10 C 3)* p^3 q ^7= 0.0425 = 4.25% Answer

    B) not more than one employee will call in sick.

    Probability that not more than one employee ...
