Assume that the Poisson distribution applies and that the mean number of hurricanes in a certain area is 7.7 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 4 years had 5 hurricanes? Does the Poisson distribution work well here? a. The probability is. (Round to three decimal places as needed.) b. The expected number of years with 5 hurricanes is (Round to one decimal place as needed.) c. The result from part (b) is V the number of hurricanes in the recent period of 45 years, so the Poisson distribution V appear to work well in the given situation.

The data records the smiling times, in seconds, of an eight-week-old baby.We will assume that the smiling times, in seconds, follow a uniform distribution between zero and 23 seconds, inclusive. This means that any smiling time from zero to and including 23 seconds is equally likely.What is the probability that a randomly chosen eight- week-old baby smiles between two and 18 seconds?
