14,15 I keep getting it wrong how do you resolve it

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, X = 1 if an odd number is rolled and X = 0 otherwise). Let Y indicate the event that 1 2, or 3 is rolled (in other words, Y = 1 if 1, 2, or 3 is rolled and Y = 0 otherwise). Find P (X = 0, Y = 1). a) 0 $6 b) 0 6 c) 0 1/3 d) 0 2/3 e) 0 1/2 f) O None of the above Question 15 Review Lat Suppose p(x, y) = *+ y 21 -, x= 1, 2, 3, y = 1, 2 is the joint pmf of X and Y. Determine P (Y = 1). a) 0 3/21 b) 0 3/7 c) 06 d) 0 1/2 e) 0 1/6 () O None of the above
