Suppose the number of telephone calls an operator receives from 9:00 to 9:05 follows a Poisson distribution with µ = 4.

(a) Find the probability that the operator will receive no calls in that time interval tomorrow.

(b) Find the probability that in the next 2 days the operator will receive a total of 3 calls in that time interval.
