Upon reviewing recent use of conference rooms at an engineering consulting firm, an industrial engineer determined the following probability distribution for the number of requests for a conference room per half-day:

(a) Currently, the building has two conference rooms. What is the probability that the number of requests will exceed the number of rooms for a given halfday?

(b) What is the probability that the two conference rooms will not be fully utilized on a given halfday?

(c) How many additional conference rooms are required so that the probability of denying a request is not more than 0.10?
