WebFor continuous random variables, we have the notion of the joint (probability) density function f X,Y (x,y)∆x∆y ≈ P{x < X ≤ x+∆x,y < Y ≤ y +∆y}. We can write this in integral form as P{(X,Y) ∈ A} = Z Z A f X,Y (x,y)dydx. The basic properties of the joint density function are • f X,Y (x,y) ≥ 0 for all x and y. 2 http://www.columbia.edu/~ad3217/joint_pmf_and_pdf/pdf.html
