Assume that the Poisson distribution applies and that the mean number of hurricanes in a certain area in 6.3 per year.
A. Find the probability that, in a year, there will be 5 hurricanes
b. In a 55-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 55 years in which 8 years had 5 hurricanes? Does the Poisson distribution work well here?
