The time spent waiting between events is often modeled using the exponential distribution. For example, suppose that an average of 30 customers per hour arrive at a store and the time between arrivals is exponentially distributed. a. On the average, how many minutes elapse between two successive arrivals? b. After the customer arrives, what is the probability that it takes more than 5 minutes for the next customer to arrive?
