Definition of joint probability

WebDefinition 5.2.1. If continuous random variables X and Y are defined on the same sample space S, then their joint probability density function ( joint pdf) is a piecewise continuous function, denoted f(x, y), that satisfies the following. f(x, y) ≥ 0, for all (x, y) ∈ R2. ∬.

This is a straightforward multi-variate generalization of the definition of the probability mass function of a discrete variable (uni-variate case). WebDefinition Marginal probability mass function. Given a known joint distribution of two discrete random variables, say, X and Y, the marginal distribution of either variable – X for example – is the probability distribution of X when the values of Y are not taken into consideration.
