Refer to the following:

Questions 16-17 use the following information. Airplanes arrive at an airport according to the Poisson distribution with a mean of 2 planes per 5 minutes. Assume that airplanes arrive independently. Question 16. In the next 10 minutes, the probability that no airplane will arrive is closest to Questions 16-17 use the following information. Airplanes arrive at an airport according to the Poisson distribution with a mean of 2 planes per 5 minutes. Assume that airplanes arrive independently. Question 17. In the next 15 minutes, the probability that \"one airplane arrives at the rst 5 minutes and no airplanes arrive in the 10 minutes after" is closest to
