A) You have two fair dice, one with three sides labeled 0,1,2 and one with 4 sides, labeled 0, 1, 2, 3. Let X1 be the outcome of rolling the first die, and X2 the outcome of rolling the second. The rolls are independent. a. What is the joint distribution of (X1, X2)? b. Let Y1 = X1 X2 and Y2 = max{X1, X2}. Make a table for the joint distribution ofY1, Y2. c. What are the marginal distribution of Y1, Y2? Are they independent?

B) Use the first part below to solve the second part. Let X1, . . . , Xn be i.i.d. continuous random variables. Find the pdf of Y1 = max{X1, . . . , Xn} and Y2 = min{X1, . . . , Xn}.
