A person with a cough is a persona non grata on airplanes, elevators, or at the theater. In theaters especially, the irritation level rises with each muffled explosion. According to Dr. Brian Carlin, a Pittsburgh pulmonologist, in any large audience you'll hear about 18 coughs per minute.
(a) Let r = number of coughs in a given time interval. Explain why the Poisson distribution would be a good choice for the probability distribution of r.

(b) Find the probability of four or fewer coughs (in a large
auditorium) in a 1-minute period. (Use 4 decimal places.)
(c) Find the probability of at least eleven coughs (in a large
auditorium) in a 30-second period. (Use 4 decimal places.)

The Denver Post reported that, on average, a large shopping center had an incident of shoplifting caught by security 1.6 times every five hours. The shopping center is open from 10 A.M. to 9 P.M. (11 hours). Let r be the number of shoplifting incidents caught by security in an 11-hour period during which the center is open. (a) Explain why the Poisson probability distribution would be a good choice for the random variable r. Frequency of shoplifting is a...
