Question (1): Three checkout counters (A, B and C) are in operation at a local supermarket. The probability of choosing checkout counters (A, B and C) are (0.2, 0.7,0,1) respectively. Two customers arrive at the counters at different times. It is assumed that the customers choose their checkout counter randomly and independently. Let X be number of times counter A is selected and Y be number of times counter B is selected by the two customers. Find the joint probability distribution of X and Y.
