We need the joint pdf of … WebFinal answer. Step 1/2. Given, X and Y are two random variables having joint pdf. f (x,y) = 2 (x + y) for 0 < y < x < 1. = 0 otherwise. To find conditional density we need to find the marginal density of X and Y. (a) To find conditional density of Y : Marginal density of X is. f (x) = ∫ f ( x, y) d y.

WebConditional pdf Suppose (X,Y ) has a joint pdf f(x,y). The marginal pdf’s of X and Y are denoted by fX(x) and fY (y). Take any x, if fX(x) > 0, then we say the conditional pdf of Y given X = x is fY (y X = x) = f(x,y) fX(x). fY (y X = x) describes the distribution of Y when we observe that the value of X is x. Take any y, if fY (y) > 0, then ...

Then the marginal pdf's (or pmf's = probability mass functions, if you prefer this terminology for discrete random variables) are defined by fY(y) = P(Y = y) and fX(x) = P(X = x).
