This definition of joint commutative distribution function (Joint Distribution Function) can be represented mathematically as-
Property 1- The joint cumulative distribution function is a monotone non-decreasing function of both x and y.
Property 2- Combined CDF is a non-negative function.
=> Fxy(x,y) ≥ 0
It is defined as the probability in the joint sample space of random variables and probability lies between 0 and 1.
Therefore joint cumulative distribution function (Joint CDF) also lies between 0 and 1.
=> It is a non-negative function
Property 3- Joint cumulative distribution function is always continuous everywhere in the xy-plane.

Definition of Joint Distribution Function (Combined CDF)
Joint CDF : [FXY(x,y)], of two random variables X and Y is defined as the probability that the random variable 'X' is less than or equal to a specified value 'x' and the random variable 'Y' is less than or equal to a specified value 'y'.🌓READ THIS ALSO:-
