    Let X be the positive difference between the scores obtained from two dice.
    a. find the probability mass function for X
    b. show that X follows a valid probability mass function
    c. Find P(X>=2)
    d. Find mu
    e. Find the variance

    [Hint: An example of a positive difference is |2-6|=4. So zero is considered a positive difference.]
