Assume that the Poisson distribution applies and that the mean number of hurricanes in a certain area is 6.6 per year. a. Find the probability that, in a year, there will be 4 hurricanes. b. In a 35-year period, how many years are expected to have 4 hurricanes? c. How does the result from part (b) compare to a recent period of 35 years in which 3 years had 4 hurricanes? Does the Poisson distribution work well here? a. The probability is (Round to three decimal places as needed.)
