# Question: Assume that each of your calls to a popular radio

Assume that each of your calls to a popular radio station has a probability of 0.02 of connecting, that is, of not obtaining a busy signal. Assume that your calls are independent.

(a) What is the probability that your first call that connects is your tenth call?

(b) What is the probability that it requires more than five calls for you to connect?

(c) What is the mean number of calls needed to connect?
