Let the random variable (X) represent the product of the number of dots facing up on each
Question:
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 \(X \geq 16\) ?
c. Define a probability model \((R(X, Y), f(x, y))\) for the random vector \((X, Y)\).
d. What is the probability that \(X \geq 16\) and \(Y \geq 8\) ?
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 \(X \geq 10\) given that \(Y=7\) ?
