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. - September 3rd 2007, 07:34 AMfinetuneReminder
