Question: Based on historical data, the probability that a major league pitcher pitches a no-hitter in a game is about 1/1300.

b. Repeat part a using the Poisson approximation to the binomial. This approximation says that if n is large and p is small, a binomial distribution with parameters n and p is approximately the same as a Poisson distribution with λ = np.
