Question

Question 4 (Conditional Independence): Suppose that X, Y, and Z are random variables that can take value 0 or 1. Suppose that the joint probability mass function of (X, Y, Z) is given by f(x, y, z) = P(X = x and Y = y and Z = z) = ?xyz where each of x, y, and z can be 0 or 1. The eight probabilities are non-negative and the sum of the probabilities must be one. If X and Y are conditionally independent when conditioning on Z, what two restrictions on the probabilities must be made?

Suppose that the joint probability mass function of (X, Y, Z) is given by f(x, y, z) = P(X = x and Y = y and Z = z) = θxyz where each of x, y, and z can be 0 or 1. The eight probabilities are non-negative and the sum of the probabilities must be one. If X and Y are conditionally independent when conditioning on Z, what two restrictions on the probabilities must be made?
