Determine the value of c that makes the function f (x, y) = c(x + y) a
Question:
Determine the value of c that makes the function f (x, y) = c(x + y) a joint probability mass function over the nine points with x = 1, 2, 3 and y = 1, 2, 3. Determine the following:
(a) P(X = 1, Y < 4)
(b) P(X = 1)
(c) P(Y = 2)
(d) P(X < 2, Y < 2)
(e) E(X), E(Y), V (X), and V (Y )
(f) Marginal probability distribution of X
(g) Conditional probability distribution of Y given that X = 1
(h) Conditional probability distribution of X given that Y = 2
(i) E(Y | X = 1)
(j) Are X and Y independent?
