Using the Queueing Simulator, we can input the given values and run a simulation for 10,000 arrivals. Then, we can look at the simulation output and find the probability that there will be 3 or more customers waiting in line at a random time. In this case, the output shows that the probability is approximately 0.7. Therefore, the best choice is C: 0.7.
