It Is Known That Between 8 and 10 A

It is known that between 8 and 10 a.m. on Saturdays, cars arrive at a toll station in Indiana at a rate of 60 per hour. Assume that a Poisson process is occurring, and that the random variable x represents the number of cars arriving at the station between 9:00 and 9:05 a.m.
