We have observed birds on airport runways and found on average, 6 birds arrive if there are no delays in landings during peak hours. Assume no delays for the next few questions.

a) What is the probability, as you observe for an hour, that at least 6 birds arrive?

b) What is the probability, as you observe for an hour, that less than 4 birds arrive?

c) What is the probability, as you observe for an hour, that no less than 4 birds arrive?

d) What is the probability, as you observe for an hour, that no more than 2 birds arrive?

e) What is the probability, as you observe for an hour, that 2 birds arrive?
