I need help with parts b to d please, I posted this twice and got wrong answers.

Answer for part a) is 1/7

(a) P(X ≤ 2, Y = 1); (b) P(X > 2, Y ≤ 1); (c) P(X > Y); (d) P(X + Y = 4).
Transcribed Image Text:(a) P(X ≤ 2, Y = 1); (b) P(X > 2, Y ≤ 1); (c) P(X > Y); (d) P(X + Y = 4).
Suppose the joint probability distribution of X and Y is given by f(x,y)= parts (a) through (d). x+y 42 for x = 0, 1, 2, 3; y = 1, 2, 3. Complete
