In fact, the joint probability of a specific value of X and a specific value of Y is zero.

the expected value of the random variable E[XjY]. It is a function of Y and it takes on the value E[XjY = y] when Y = y. So by the law of the unconscious whatever, E[E[XjY]] = X y E[XjY = y]P(Y = y) By the partition theorem this is equal to E[X]. So in the discrete case, (iv) is really the partition theorem in disguise. In the continuous case Remember that for a discrete random variable $X$, we define the PMF as $P_X(x)=P(X=x)$. Now, if we have two random variables $X$ and $Y$, and we would like to study
