Question
Airline passengers arrive randomly and independently at the passenger-screening facility at a major international airport. The mean arrival rate is 10 passengers per minute, and passenger arrivals follow a Poisson distribution. (Round your answers to six decimal places.) solve and Compute the probability that three or fewer passengers arrive in a one-minute period. solve and Compute the probability of no arrivals in a 21-second period. solve and Compute the probability of at least one arrival in a 21-second period.
