We have two fair three-sided dice, indexed by i = 1,2. Each die has sides labelled 1, 2,and 3. We roll the two dice independently, one roll for each die. For i = 1, 2, let therandom variable X¿ represent the result of the ith die, so that X; is uniformly distributedover the set {1,2,3}. Define X = X₂ − X₁.(a) Determine the PMF, expected value and variance of X.(b) Let Y = X². Find the PMF of Y.

(a) Given, Xi is uniformly distributed over the set 1,2,3 Now to determine the PMF of X ,we can…
