Suppose the probability that a softball player gets a hit in any single at-bat is 0.300. Assuming that her chance of getting a hit on a particular time at bat is independent of her other times at bat, what is the probability that she will not get a hit until her fourth time at bat in a game?

(a) a 4

3 b(0.3)1(0.7)3

(d) (0.3)3(0.7)1

(b) a 4

3 b(0.3)3(0.7)1

(e) (0.3)1(0.7)3

(c) a 4

1 b(0.3)3(0.7)1
