The Exponential Distribution · Exercise 38

In major league baseball, a no-hitter is a game in which a pitcher, or pitchers, doesn't give up any hits throughout the game. No-hitters occur at a rate of about three per season. Assume that the duration of time between no-hitters is exponential.

(a) What is the probability that an entire season elapses with a single no-hitter?
(b) If an entire season elapses without any no-hitters, what is the probability that there are no no-hitters in the following season?
(c) What is the probability that there are more than 3 no-hitters in a single season?
