A Taxi operator has two cars, which hehires out day by day. The number ofdemands for a car on each day isdistributed as a Poisson distributionwith mean 1.5. Calculate theproportion of days on which neithercar is used and the proportion of dayson which same demand is refused. Ifeach car is used an equal number oftimes, on what proportion of days isone of the cars not used.
