Question

the
c.d.f of bivarate discrete random variable (x,y) is given by F(x,y)={1/8 for x=1,y=1;
5/8 for x=1/,y=2;
1/4 for x=2,y=1;
1 for x=2,y=2;
find a).j.p.m.f of (x,y)
b).m.p.m.f of x
c).m.p.m.f of y​

Answer 1

Answer:

A discrete bivariate distribution represents the joint probability distribution of a pair of random variables. ... Each row in the table represents a value of one of the random variables (call it X) and each column represents a value of the other random variable (call it Y).

Answer 2

Answer:

Definition: Let X and Y be two discrete random variables defined on the sample space S of a random experiment then the function (X, Y) defined on the same sample space is called a two-dimensional discrete random variable.
