Unformatted text preview: Î» (from formula sheet). (a) P(X > 1) = exp(Î» x) = exp([1/1.5]1) = exp(2/3) = 0.5134. (b) If you did not receive a message in the last four hours what is the probability that your do not receive a message in the next hour?(4 pts) (b) P(X > 5/ X > 4) = (by loss of memory property) = P(X > 1) = 0.5134 (from (a) above). (c) What is the expected time between your fourth and fifth message? (2 pts) Same as E(X) = 1.5 hours....
