On the average, 2 airplanes per minute land at a certain airport. We would like to model the number of landings by a Binomial counting process.

(a) What frame length gives the probability 0.1 of one landing during any given frame?

(b) Using the chosen frame, compute the probability of 10 landings during the next 5 minutes.

(c) Using the chosen frame, compute the mean of the number of landings during the next 5 minutes.

(d) Using the chosen frame, compute the standard deviation of the number of landings during the next 5 minutes.
