1. Customers arrive at a carwash on average once every 20 minutes. It seems likely that customer arrivals follow an exponential distribution. For each of these random numbers, calculate the simulated time between arrivals at the carwash

2. A manager is simulating the number of times a machine operator stops a machine to make adjustments. After careful study the manager found that the number of stops ranged from one to five per cycle and that each number of stops was equally likely. Using the random numbers 0.11 and 0.5 (in that order), determine how many stops for adjustments each of the next two cycles will have.
