SpletFind the pdf of Z = XY. Transformation of random variables. If B and C are two independent random variables with a given density function then we can find the distribution of a new variable, say {eq}Z = B/C{/eq} by first computing the cumulative distribution of Z and then differentiating it to find the probability density function. Splet(a). Find P(X +Y ≤ 1). (b). Find the cdf and pdf of Z = X +Y. Since X and Y are independent, we know that f(x,y) = fX(x)fY (y) = ˆ 2x·2y if 0 ≤ x ≤ 1 and 0 ≤ y ≤ 1 0 otherwise We start … SpletAnswer (1 of 2): I don’t know what you mean by 1/1, but the details say you want the distribution of the sum. The joint PDF is just 1 on the square with corners at (-1, 0), (-1, 1), (0, 0) and (0, 1). Now Z+1 = (X+1) + Y, and X+1 and Y are now both independently uniform on (0, 1). Then X+Y is in... cheltenham festival 2022 racing
