A tetrahedron shaped die gives one of the numbers 1, 2, 3, 4 with equal probabilities. We roll two of these dice and denote the two outcomes by X1 and X2. Let Y1 " minpX1, X2q and Y2 " |X1 ´ X2|. (a) Find the joint probability mass function of X1 and X2. (b) Find the joint probability mass function of Y1 and Y2. (c) Compute ErY1Y2s.
