a. Find the probability that in a year, there will be no hurricanes. b. In a 55-year

Question:

a. Find the probability that in a year, there will be no hurricanes.
b. In a 55-year period, how many years are expected to have no hurricanes?
c. How does the result from part (b) compare to the recent period of 55 years in which there were no years without any hurricanes? Does the Poisson work well here?
Assume that the Poisson applies; assume that the mean number of Atlantic hurricanes in the United States is 6.1 per year, as in Example 1; and proceed to find the indicated probability.
