5.32 Pet Peeves Across the board, 22% of car leisure travellers rank "traffic and other drivers" as their pet peeve while travelling. Of car leisure travel- lers in the densely populated U.S. Northeast, 33% list this as their pet peeve. A random sample of n = 8 such travellers in the Northeast were asked to state their pet peeve while travelling. The MINITAB printout shows the cumulative and individual probabilities.

a. Use the binomial formula to find the probability that all eight give "traffic and other drivers" as their pet peeve.

b. Confirm the results of part a using the MINITAB printout.

c. What is the probability that at most seven give "traffic and other drivers" as their pet peeve?
