Extracted text: Let X = the time between two successive arrivals at the drive-up window of a local bank. If X has an exponential distribution with 1 = 1, (which is identical to a standard gamma distribution with 1), compute the following. (If necessary, round your answer to three decimal places.) αΞ (a) The expected time between two successive arrivals 1 (b) The standard deviation of the time between successive arrivals 1 (c) P(X < 3)="" (d)="" p(2="">< x=""><>
