Let X 5 the time between two successive arrivals at the drive-up window of a local bank. If X has an exponential distribution with l 5 1 (which is identical to a standard gamma distribution with a 5 1), compute the following: a. The expected time between two successive arrivals b. The standard deviation of the time between succes- sive arrivals c. P(X
