    Combinations Problem.

    PLEASE HELP

    Jim pitches for baseball. He can either:
    a. give up no runs.
    b. give up 1 or 2 runs.
    c. give up 3 or 4 runs.
    d. give up at least 5 runs.

    1. Jim makes 9 starts. In how many ways can the number of runs be distributed? (order of starts is irrelevant)

    I got (9+4-1 = 12) _{12}C_{9} or \frac{12!}{9!3!}

    2. Assuming each outcome for the season is equally likely, what is the probability that Jim pitches at least 3 shutouts? (Shutout = Jim gives up no runs)

    No idea how to go about doing this one. Help would really be appreciated.
