21. Suppose X and Y are the random variables with joint PMF given by: X\\Y123 0.1 0.3 0.1 2 0.2 0 0.1 3 0 0.1 0.1 22. 23. Compute EX. Answer: Suppose X and Y are random variables with the same joint PMF given in question. Compute P(X = 1|Y = 2). Answer: Suppose X and Y are random variables with the same joint PMF given in question Find the expected value of X given the information that X + Y is even (i.e. E(X|X + Y is even))
