For three categorical variables X, Y and Z: a. When Y is jointly independent of X and Z, show that X and Y are conditionally independent, given Z. b. Prove that mutual independence of X, Y and Z implies that X and Y are both marginally and conditionally independent. c. When X is independent of Y and Y is independent of Z, explain why X is not necessarily independent of Z.
