Find the probability that on any given day exactly none, one, two and 3 cars will be hired, and determine the mean number of cars hired per day. 5.1.2. The cost of hiring a car is R25 per day, and the total outgoings per car irrespective of whether or not it is hired, are R5 per day. Determine the expected daily profit from hiring these 3 cars.
