Review Test Submission: Quiz4 (Solved)Qatar post branch at has two cashier lines, one of which is known to be faster than the other. Let X1 denotes the number of customers in the first line and X2 denotes the number of customers in the fast line at the same time of the day. Suppose the joint p.m.f. of X1 and X2 is given by 3. What is the probability that the total number of customers in the two lines is exactly four?Qatar post branch at has two cashier lines, one of which is known to be faster than the other. Let X1 denotes the number of customers in the first line and X2 denotes the number of customers in the fast line at the same time of the day. Suppose the joint p.m.f. of X1 and X2 is given by The joint probability distribution is1-Calculate the covariance between X and YQatar post branch at has two cashier lines, one of which is known to be faster than the other. Let X1 denotes the number of customers in the first line and X2 denotes the number of customers in the fast line at the same time of the day. Suppose the joint p.m.f. of X1 and X2 is given by 2- What is the probability that both lines have the same length (i.e. same number of customers)?Qatar post branch at has two cashier lines, one of which is known to be faster than the other.
