4. Students arrive at a tutoring center to a Poisson process with a rate of 10 per hour.(a) What is the probability that the second arrival is observed less than 15 minutes after the firstarrival?(b) What is the probability that the third arrival is observed less than 10 minutes after the secondarrival if it has not yet been observed 5 minutes after the second arrival?(c) What is the probability that more than 20 minutes is required for the third arrival?(d) Suppose a volunteer working at the center has a 6-hour shift. Compute the expected value andthe variance for the number of students who would arrive during her shift.

8. You manage a call center and your job is to make sure the employees aren't slacking off when they are on the clock. You notice that one employee goes 20 minutes without picking up the phone, and you know the expected time between calls is 2 minutes. Derive an upper bound for the probability that the employee didn't receive a call during the 20 minutes.
