Practice Test 5

A Monte Carlo program estimates how long a cafeteria line might take during lunch. It uses random values for arrival times and service times to represent day-to-day changes. Randomness is necessary because students arrive in bursts and workers serve at different speeds. One simulation shows a 6-minute wait, while another shows a 14-minute wait with the same settings. Based on the scenario above, what is the role of randomness in this simulation?

A program simulates daily weather for a class project using random values for temperature and precipitation. Temperatures range from 40°F to 95°F, and precipitation can be none, rain, or snow. Randomness models real-world uncertainty, since weather changes without a fixed pattern. Some weeks become mostly sunny, while others include several rainy days. Based on the scenario above, how do random values affect the outcome of this weather simulation?
