Harv& Marv’s Outback Alaska provides personalized 4-hour or 8-hour whale watching tours in Juneau Alaska.

(Count Deb and I as two very satisfied customers.) Suppose the number of whales spotted during a 4-hour tour follows the Poisson distribution and averages 5.3.

a. What is the probability that exactly three whales will be spotted during the next 4-hour tour?

b. What is the probability that less than four whales will be spotted during the next 4-hour tour?

c. What is the probability that more than five whales will be spotted during the next 4-hour tour?

d. What is the probability that exactly six whales will be spotted during the next 8-hour tour?
