---### Calculating Expected Difference in Check-Out Line CustomersA certain market has both an express checkout line and a super-express checkout line. Let \( X_1 \) denote the number of customers in line at the express checkout at a particular time of day, and let \( X_2 \) denote the number of customers in line at the super-express checkout at the same time. Suppose the joint probability mass function (pmf) of \( X_1 \) and \( X_2 \) is given in the accompanying table.| \(X_1 \backslash X_2\) | 0 | 1 | 2 | 3 ||:----------------------:|:------:|:------:|:------:|:------:|| 0 | 0.08 | 0.06 | 0.04 | 0.00 || 1 | 0.08 | 0.13 | 0.05 | 0.05 || 2 | 0.05 | 0.04 | 0.10 | 0.06 || 3 | 0.04 | 0.03 | 0.06 | 0.07 || 4 | 0.00 | 0.01 | 0.05 | 0.06 |#### Explanation of the TableThe rows in the table represent the values of \( X_1 \) (number of customers in the express checkout line), while the columns represent the values of \( X_2 \) (number of customers in the super-express checkout line). Each cell in the table contains the joint probability \( P(X_1 = x_1, X_2 = x_2) \).To calculate the expected difference between the number of customers in line at the express checkout and the number in line at the super-express checkout, we define \( D = X_1 - X_2 \). We then compute the expected value \( E(D) \) using the joint pmf.#### Calculation Steps1. Compute the expectations \( E(X_1) \) and

The joint probability distribution table provided in the question is as follows :-…
