  1. You can find the probabilities by using a binomial probability table or do these problems by hand using the following:

    P(x) = (nCx)(p^x)[q^(n-x)]
    n = 10
    p = .80
    q = 1 - p

    I'll give you some hints:
    b. Find P(10).
    c. Find P(8), P(9), and P(10), then add together for total probability.
    d. I'll let you determine this one.
