Typically the wait time probability density function is described by exponential distribution, where:
( ) , for , where is the average waiting time.
At a famous worldwide coffee franchise, the average wait time for any customer before being served is
1) Find the probability that the customer needs to wait for more than minutes.
2) Find the probability that a customer will be served in
