A car rental company has rental offices at both Kennedy and LaGuardia airports. Assume that a car rented at one airport must be returned to one of the two airports. If the car was rented at LaGuardia the probability it will be returned there is 0.8; for Kennedy the probability is 0.7. Suppose that we start with 1/2 of the cars at each airport and that each week all of the cars are rented once. (a)What is the fraction of cars at LaGuardia Airport at the end of the first week?
(b) At the end of the second?
(c) In the long run?

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.
