Please help me understand steps and answer. Thanks.

Two dice are rolled and the two resulting values are multiplied together to form the quantity z What is the variance of the random variable z? Please round your numerical answer to the nearest integer. Note: the probability of an outcome, say 4, on the second die is 1/6, no matter what the outcome of the first die. Hence the two random variables corresponding to the values on the two dice are independent. And if two random variables are independent, then they are uncorrelated
