2. Someone claims that the waiting time, in minutes, between hits at a certain website has an exponential distribution with parameter λ = 1. a. Let X be the waiting time until the next hit. If the claim is true, what is P(X ≥ 5)? b. Based on the answer to part (a), if the claim is true, is five minutes an unusually long time to wait? Explain.
