Assume that the arrival times of hits on a certain website follow a Poisson Process with a mean rate of 4 per minute a) A. Let X be the number of hits that arrive in the next minute. Find P(X = 6). B. Let y be the number of hits that arrive in the next 45 seconds. Find P(Y > 2) C. Let T be the waiting time until the next hit arrives. Find PT > 1) D. Let T be the waiting time until the 5th hit arrives. Find the mean and variance of T and P(TS2)
