Suppose that in a production of spark plugs the fraction of defective plugs has been constant at 2 % over a long time and that this process is controlled every half hour by drawing and inspecting two just produced. Find the probabilities of getting (a) no defectives, (b)1 defective, (c) 2 defectives. What is the sum of these probabilities?
