Flying over the western states with mountainous terrain in a small aircraft is 40% riskier than flying over similar distances in flatter portions of the nation, according to a General Accounting Office study completed in response to a congressional request. The accident rate for small aircraft in the 11 mountainous western states is 2.4 accidents per 100,000 flight operations.

(a) Letr = number of accidents for a given number of operations. Explain why the Poisson distribution would be a good choice for the probability distribution ofr.

Frequency of accidents is a rare occurrence. It is reasonable to assume the events are independent.Frequency of accidents is a common occurrence. It is reasonable to assume the events are independent. Frequency of accidents is a common occurrence. It is reasonable to assume the events are dependent.Frequency of accidents is a rare occurrence. It is reasonable to assume the events are dependent.

(b) Find the probability of no accidents in 100,000 flight operations. (Use 4 decimal places.)

(c) Find the probability of at least 8 accidents in 200,000 flight operations. (Use 4 decimal places.)
