  1. Use the binomial probability function:

    P(x) = nCx(p^x)[q^(n-x)]

    n = 20
    x = 10
    p = 0.45
    q = 1 - p = 0.55

    Substitute into the function and go from there.

    Note:
    You can also use a binomial probability function table with the values listed to find the probability as well. It is an easier way of doing this problem.

    I hope this will help get you started.
