Random variables

  1. May 16, 2005 #1
    Hi, I really need help with joint PDF, if anyone can help, that would be super! :smile:

    Random Variables X and Y have joint PDF
    fx,y (x, y) = 1/2 if -1 <= x <=y <= 1, and it is 0 otherwise

    a) what is fy (y)?

    b) what is fx|y (x|y)?

    c) what is E[X|Y = y]?
