FestEvents is a concert organizer that is evaluating the installation of portable toilets at an outdoor venue where a concert is going to take place. In particular, it is considering an area of the venue that is far away from the existing restrooms. Assume there will be one single queue to access all the portable toilets in this area and that only one person uses a toilet at a time.   FestEvents estimates that there will be 4 arrivals per minute on average to the toilets, with a standard deviation of the time between arrivals of 15 seconds. The average time a person spends using the toilet is 3.12 minutes with a standard deviation of 2 minutes. Suppose FestEvents installs 20 portable toilets.   a) On average, what fraction of the toilets will be occupied during the event? 

CPU-on-Demand (CPUD) offers real-time high-performance computing services. CPUD owns 7 supercomputers that can be accessed through the Internet. Their customers send jobs that arrive on average every 4 minutes. The standard deviation of the interarrival times is 4 minutes. Executing each job takes on average 16 minutes on one of the supercomputers (during this time, the computer cannot perform any other work). The standard deviation of this processing time is 24 minutes.   a) What is the utilization (as a %) of the supercomputers?
