Problem 5E

Roll a pair of four-sided dice, one red and one black. Let $$X$$  equal the outcome on the red die and let $$Y$$ equal the sum of the two dice.

(a) On graph paper, describe the space of $$X$$  and Y.

(b) Define the joint pmf on the space (similar to Figure 4.1-1).

(c) Give the marginal pmf of $$X$$ in the margin.

(d) Give the marginal pmf of $$Y$$ in the margin.

(e) Are $$X$$ and $$Y$$ dependent or independent? Why or why not?
