Basically, two random variables are jointly continuous if they have a For n n jointly continuous random variables X1 X 1, X2 X 2, ⋯ ⋯, Xn X n, the joint PDF is defined to be the function fX1X2 Xn(x1,x2,,xn) f XXX n (x 1, x 2,, x n) such The joint distribution of two continuous random variables can be specified by a joint pdf, a surface specifying the density of \((x, y)\) pairs.
