WBd-OT: Emergency calls in a 911 line occur at a rate of one raven;r two hours following a I Poisson process. a) What is the probability that the line will have no calls during a five-hour period? 36 y!!! WB4-09: Suppose for a long-established speed trap the number of speeders follows a Poisson process with an average of 4 per hour. Let X be the number of hours after the start of the trap (officer manning the trap). a) What is the probability it will take between 2 and 5 hours to catch the 10th speeder in the trap? b) What is the probability of catching the 5th speeder in the trap in at most 3 hours?\f\"34.14: The lifetime of a certain Wile 0f 60'\"me Chill follows an exponential distribution with an average life OonLhom>W12ea w W S- W: le hip will last at least 50 hours?
