A supermarket has two customers waiting for their purchases at counter 1 and one customer waiting to pay at counter 2. Let X1 and X2 denote the numbers of customers who spend more than RM50 on groceries at the respective counter. Suppose that X1 and X2 are independent binomial random variables, with the probability that a customer at the counter I will spend more than RM50 equal to 0.2 and the probability
