Question 14 Suppose that a fair, 6 sided die is rolled. Let X indicate the event that an odd number is rolled (in other words, = 1 if an odd number is rolled and X = 0 otherwise). Let Y indicate the event that 3, 4, or 5 is rolled (in other words, Y = 1 if 3, 4, or 5 is rolled and Y = 0 otherwise). Find P (X = 0, Y = 1). a) 0 2/3 b ) 0 1/ 2 c) 0 6 d) 0 1/3 e) 0 1/6 f) O None of the above Question 15 Review Later Suppose p(x, y) = +2y 30 , x= 1, 2, 3, y = 1, 2 is the joint pmf of X and Y. Determine P (Y = 1). a) 0 1/6 b) 04/15 c) 0 1 / 2 d) 0 2/5 e) 0 6 f) O None of the above
