A parking lot has two entrances. Cars arrive at Entrance 1 according to a Poisson Probability Distribution at an average of thre
e per hour and at Entrance 2 according to a Poisson Probability at an average of four per hour. What is the probability that a total of three cars will arrive at the parking lot in a given hour. What is the probability that a total of three will arrive at the parking in a given hour? Assume that the numbers of cars arriving at the two entrances are independent. [Hint: This is hard but not as hard as you think].
Since the amount of money (r) is a function of the time (t) we will make it the y-value. t is how much time and he gets $15 a minute so we multiply t by 15. 500 is how much he gets paid for doing it. If he showed up and just left, he would still get 500.
