    The first question is asking you to prove that P(X,Y)=g(x)h(y).

    Yes but

    I have just done ist part but i am feeling difficulty in the following parts
    2, 3, and 4th part of the question.
    1st question is from Joint Distributions.
    which formula will be use for f(x/1) and for P(X=2/Y=1) here are 2 formula's
    Conditional probability function for X given Y=y
    1.X given Y=y
    f(xi|yj)=P(X=xi|Y=yj)
    =P(X=xi and Y=yj)/P(Y=Yj)
    =f(xi,yj)/h(yj) for i=1,2,....j=1,2

    2. Conditional probability function for Y given X=x
    f(yj|xi)=P(Y=yj|X=xi)
    =P(Y=yj and X=xi)/P(X=xi)
    =f(xi,yj)/g(xi), where g(x)>0.

    also need help for 2nd question
    Thank you.
