Assume that the Poisson distribution applies and that the mean number of hurricanes in a certain area is 7.1 per year.

a. Find the probability​ that, in a​ year, there will be 5 hurricanes.

b. In a 45 year period, how many years are expected to have 5 hurricanes?

c. How does the result from part​ (b) compare to a recent period of 45 years in which 5 years had 5 hurricanes? Does the Poisson distribution work well​ here?
