Question

At one of New York’s traffic signals, if more than 17 cars are held up at the intersection, a traffic officer will intervene and direct the traffic. The hourly traffic pattern from 12:00 p.m. to 10:00 p.m. mimics the random numbers generated between 5 and 25. (This holds true if there are no external factors such as accidents or car breakdowns.)
