Problem 87E

The number of requests for assistance received by a towing service is a Poisson process with ? = 4 rate per hour. a. ?Compute the probability that exactly ten requests are received during a particular 2-hour period. b. ?If the operators of the towing service take a 30-min break for lunch, what is the probability that they do not miss any calls for assistance? c.? ?How many calls would you expect during their break?

Step-by-Step Solution:

Answer : Step 1 of 3 : Given, The number of requests for assistance received by a towing service is a Poisson process with = 4 rate per hour. a) The claim is to compute the probability that exactly ten requests are received during a particular 2-hour period. Let X be the number of requests are received during a particular 2-hour period. x Therefore, P(X = 10) = e x! Where, = 2 = 2×4 = 8 e8810 P(X = 10) = 10! = 0.09926 Therefore, the probability that exactly ten requests are received during a particular 2-hour period is 0.09926
