  1. Answer:

    The mean is 21.12.

    Step-by-step explanation:

    Binomial probability distribution

    Probability of exactly x successes on n repeated trials, with p probability.

    The expected value of the binomial distribution is:

    [tex]E(X) = np[/tex]

    In this question:

    [tex]n = 48, p = 0.44[/tex]

    Mean:

    [tex]E(X) = np = 48(0.44) = 21.12[/tex]

    The mean is 21.12.
