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.

Let x e {1, 2} and y e {1, 4}, consider a predicate P(x, y) defined as P(x, y): 4 divides (x² + 3y). Rewrite the expression 3y[VxP(x, y)] by eliminating the quantifiers and replace P(x, y) with 4 divides (x² + 3y). Hence, determine the truth value of the statement.

A roulette wheel has 30 slots, consisting of 2 blues, 8 whites, and 20 red slots. You will receive P100 if the roulette stops spinning on a blue slot, you will receive P50 on a white slot, but you will be penalized P10 if the roulette stops spinning on a red slot. Let X be the amount you will recieve (or pay). The probaility of receiving P50 is 2/30 or 1/15, and of receiving P50 is 8/30 or 4/15. What is the probability of penalty of P10? 2/3 1/3 -2/3
