Suppose the number of phone calls passing through a particular cellular relay system, follows a Poisson distribution with an average of 3 calls during a 1-min period. (A) Find the probability, p, that no call will pass through the relay system during a given 2-min period. (B) Find the probability that at least four minutes will pass before a call is passed through the relay system.
