Meteor showers can be a spectacular sight. They are especially intense in late July and early August, when the annual Perseid meteor shower is visible in the early morning sky. As many as 50 to 150 meteors per hour are visible. Suppose you are watching on the morning of August 12. Assuming all the Poisson conditions are met and that the average rate of appearance is 90 meteors per hour—or 1.5 meteors per minute—use the Poisson table to determine the probability of
a. Exactly three meteors in a random minute.
b. At least five meteors in the next minute.
c. No more than one meteor in the next five minutes.
d. Between two and four meteors in the next two minutes.
