Let the random variable X represent the product of the number of dots facing up on each die after a pair of fair dice is rolled. Let Y represent the sum of the number of dots facing up on the pair of dice.
a. Define a probability model (R(X),f (x)) for the random variable X.
b. What is the probability that X 16?
c. Define a probability model (R(X,Y),f(x,y)) for the random vector (X,Y).
d. What is the probability that X 16 and Y 8?
e. Are X and Y independent random variables?
f. Define the conditional PDF of X given that Y = 7.
g. What is the probability that X 10 given that Y = 7?
