Assume that the Poisson distribution applies and that the mean number of hurricanes in a certain area is 5.6 per year.

a. Find the probability​ that, in a​ year, there will be 3 hurricanes.

b. In a 35​-year ​period, how many years are expected to have 3 ​hurricanes?

c. How does the result from part​ (b) compare to a recent period of 35 years in which 3 years had 3 ​hurricanes? Does the Poisson distribution work well​ here?
