Question

Please Answer the following two questions. I am stuck with these. Thanks.

Approximately 18% of the calls to an airline reservation phone line result in a reservation being made . (a) Suppose that an operator handles 15 calls. What is the probability that none of the 15 calls result in a reservation? (Give the answer to 3 decimal places.) (b) What assumption did you make to calculate the probability in Part (a)? 0 Calls are independent. O Calls are dependent. (c) What is the probability that at least one call results in a reservation being made? (Hint: Use your answer to Part (a). Give the answer to 3 decimal places.)

Explanation / Answer

a)P(call not results in reservation) = 1-0.18 = 0.82

P(15 call not results in reservation) = 0.82^15 = 0.051

b) Independent

c)P(Alteast 1 call out of 15 results in reservation) = 1- P(15 call not results in reservation) = 1-0.051 = 0.949
