Question

A market has two check out lines. Let X be the number of customers at the express checkout line at a particular time of day. Let Y denote the number of customers in the super-express line at the same time. The joint probability mass function of (X, Y) is given below. What is the probability of having only one customer at the express checkout line when there are more than two customers in the super-express line at the same time

Answer 1

To find the probability, we need additional information or the joint PMF values.

Step-by-step explanation:

To find the probability of having only one customer at the express checkout line when there are more than two customers in the super-express line, we can use the joint probability mass function (PMF) of (X, Y). However, the joint PMF is not provided in the given information, so we cannot calculate the exact probability. We need additional information or the specific values of the joint PMF to proceed with the calculation.
