WebJoint Probability Distributions: So far we have analyzed single random variables, and groups of independent random variables. Real applications often produce multiple dependent random variables We will primarily discuss bivariate distributions (which have two variables X and Y) These variables can either be discrete or continuous but have the … WebRecall: conditional probability distributions I It all starts with the de nition of conditional probability: P(AjB) = P(AB)=P(B). I If X and Y are jointly discrete random variables, we can use this to de ne a probability mass function for X given Y = y. I That is, we write p XjY (xjy) = PfX = xjY = yg= p(x;y) p Y (y) I In words: rst restrict sample space to pairs (x;y) with given
