Suppose two random variables X and Y will be jointly used for a simulation model. Their joint density function is f(x, y) = xe **{y+"), where both X and Y are positive-valued random variables. (a) Please find the marginal probability density functions of X and Y, respectively. (4 points) (b) Please find the conditional probability density function of X given Y = y. (4 points) (c) Please find the conditional probability density function of Y given X = x. (4 points) (d) If the simulation output is determined by a variable z, where Z= XY , please find the cumulative distribution function (CDF) of z. (4 points) (e) Please find the probability density function of z and f(z= 4) = ? (4 points)
