Phone calls arrive at a switchboard at an average rate of λ = 2 per minute. Assume that the number of calls in a minute follows the Poisson distribution with parameter λ. (a) What is the probability that exactly two calls arrive in a minute? (b) Find the probability that more than two calls arrive in a minute
