**a.**

To determine

Develop an empirical bivariate probability distribution for number of snack items and the number of reading materials in a randomly selected customer purchase.

Find the probability of a customer purchase consisting of one item of reading materials and two snack items, probability of a customer purchasing one snack item and to explain why the probability,

**b.**

To determine

Show the marginal probability distribution for the number of snack items purchased and compute its expected value and variance.

**c.**

To determine

Compute the expected value and variance for the number of reading materials purchased by a customer.

**d.**

To determine

Show the probability distribution for total number of items in a customer purchase and to compute its expected value and variance.

**e.**

To determine

Compute the covariance and correlation coefficient between *x* and *y.*

Identify the relationship between the number of reading materials and the number of snacks purchased on a customer visit.
