During lunch hour, customers arrive at a fast-food drive-through window, on average, every $2.5$ minutes. Assume arrival time follows the exponential probability distribution. a. What is the probability that the next customer will arrive 1. within the next 2 minutes? 2. in more than 5 minutes? 3. between 1 and 4 minutes? b. Confirm the answers to part a using Excel.
