find their Joint PMF. Marginal PMF in case of more than two discrete random variables Suppose X₁, X₂, . . . , Xₙ are jointly distributed discrete random variables with joint PMF Fₓ₁,ₓ₂,….ₓₙ The PMF of the individual random variables X₁, X₂, . . . , Xₙ are called as marginal PMFs. It can be shown in
