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) or

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 wouldreallybe appreciated.
