The exponential distribution is frequently applied to the waiting times between successes in a Poisson process. If the number of calls received per hour by a telephone answering service is a Poisson random variable with parameter λ = 6, we know that the time, in hours, between successive calls has an exponential distribution with parameter β =1/6. What is the probability of waiting more than 15 minutes between any two successive calls?

Consider a customer arrival process that is a Poisson process. To find the probabilities described below, which of the following random variable selections (as Poisson, Exponential or k-Erlang) is correct? to find the probability that the time between the 2nd and 3rd customer arrivals is 5 minutes, use a k-Erlang random variable with k>1 to find the probability that 10 customers arrive during a 30-minute period, use a k-Erlang random variable to find the probability that the total time elapsed...

The number of automobiles entering a tunnel per 2-minute period follows a Poisson distribution. The mean number of automobiles entering a tunnel per 2-minute period is four. (A) Find the probability that the number of automobiles entering the tunnel during a 2- minute period exceeds one. (B) Assume that the tunnel is observed during four 2-minute intervals, thus giving 4 independent observations, X1, X2, X3, X4, on a Poisson random variable. Find the probability that the number of automobiles entering...
