The number of requests for assistance received by a towing service is a Poisson process with a mean rate of 3 requests per hour. (a) Compute the probability that exactly 4 requests are received during a 1-hour period. (Round your answer to 4 decimal places.) (b) Compute the probability that the operator of the towing service will have to wait longer than 4 hours before receiving the tenth request. (Round your answer to 4 decimal places.)
