WebJoint probability distributions: Discrete Variables Probability mass function (pmf) of a single discrete random variable X specifies how much probability mass is placed on each possible X value. The joint pmf of two discrete random variables X and Y describes how much probability mass is placed on each possible pair of values (x, y): p WebThe marginal distribution P ( Z) is obtained by integrating/collapsing over W. Both cases show that the joint distribution of Z and W is zero when W falls outside [ 0, 1], so it's only necessary to integrate over W ∈ [ 0, 1]. …
