Of the 25 computers available in the supply room, 10 have circuit boards for a printer, 5 have circuit boards for a modem, and 13 have neither type of board. Use P to denote computers that have printer boards and M to denote computers that have modem boards. Symbolically denote the following events and find the probability of each of these events for randomly selected computers from the supply room. Hint: draw a Venn-diagram (a) Those that have both boards. (b) Those that have at least one of these two boards. (c) Those that have printer boards only.
