1. Consider a gas station. There is a single gas pump and one automatic washer. Including the car getting the gas, there can be 5 cars in front of the pump. If a car arrives at a time there are five cars in front of the pump including the car receiving gas, an arriving car leaves (and is lost). After filling the tank car goes to car wash with probability p and leaves the station with probability (1p). Total number of cars waiting in front of the car wash including the car being washed is 4 . If a car decides to go to car wash (with probability p ) and the space in front of the car wash is full it is blocked until a car leaves the gas station. Draw the flowcharts of the arrival and departure events from the gas pump
