    Hi,
    I am relatively new to stats and trying to get my head around it. The question is :

    A

    What remains if I marginalize a joint distribution  Pr(v,w,x,y,z) over five
    variables with respect to variables w and y? What remains if I marginalize the resulting distribution with respect to v ?


    B
    Show that the following relation is true:
    Pr(w,x,y,z) = Pr(x,y) Pr(z|w,x,y)Pr(w|x,y):


    I know generally speaking that:


     Pr(x) = \int Pr(x,y) dy

    Would be grateful if someone could point me in the right direction please!

    Thanks
