A Taxi operator has two cars, which he hires out day by day. The number of demands for a car on each day is distributed as a Poisson distribution with mean 1.5. Calculate the proportion of days on which neither car is used and the proportion of days on which same demand is refused. If each car is used an equal number of times, on what proportion of days is one of the cars not used.
