    Generateing a random variable




    Hi, I have a problem on how to start the following problem:

    Suppose that X and Y are discrete random variables with a joint probability
    mass function p_XY (x, y).

    Procedure is the following:
    a. Generate X ∼ p_X (x).
    b. Accept X with probability p(y|X).
    c. If X is accepted, terminate and return X. Otherwise go to Step a.

    Show that this procedure generates a random variable X ∼ p_X|Y (x|y).


    I would've been grateful for any help. Tnx

    I don't have emotions and sometimes that makes me very sad.
