a blue die, and a white die --- and recording the number rolled on
each die. Assume that the dice are fair, so that all outcomes are
equally likely. (1) What probability should be assigned to each
outcome? equation editorEquation Editor (2) What is the probability

A fair die is rolled. If the result is greater than 4, a fair
coin is flipped, and otherwise, an unfair coin with P[H] = 2/3 is
flipped. The outcome of the die roll is mapped to X, and the
outcome of the coin flip is mapped to Y , with 1 for heads and −1
for tails.

(b) Find both marginal PMFs. Do the marginal PMFs indicate
independence?
