Exercise 1.44. Two fair dice are rolled. Let X be the maximum of the two numbers and Y the minimum of the two numbers on the dice. (a) Find the possible values of X and the possible values of Y . (b) Find the probabilities P(X ≤ k) for all integers k. Find the probability mass function of X. Hint. Noticing that P(X = k) = P(X ≤ k) − P(X ≤ k − 1) can save you some work. (c) Find the probability mass function of Y .
