	Cancellations are not independent.
	Most likely cancellations arrive independently.

(b)

What is the probability that no cancellations will occur on a particular Wednesday? (Round your answer to 4 decimal places.)

Probability

(c)

What is the probability that one cancellation will occur on a particular Wednesday? (Round your answer to 4 decimal places.)

Probability

(d)

What is the probability that more than two cancellations will occur on a particular Wednesday? (Round your answer to 4 decimal places.)

Probability

(e)
