Problem 6.2.1 Solution We are given that W = X +Y and that the joint PDF of X and Y is fX,Y (x,y) = ˆ 2 0 ≤ x ≤ y ≤ 1 0 otherwise (1) We are asked to ﬁnd the PDF of W. The ﬁrst step is to ﬁnd the CDF of W, FW(w). Note

WebbOnce we establish part (b), the proof of part (a) is easy: if X and Y are bounded, then their mgf’s exist for all t and thus their cdf’s are the same iff their moments are the same for any order. The condition that the mgf exists in a neighborhood of 0 is important. There are random variables with ﬁnite moments of any order, but their Webb71 Likes, 1 Comments - Miss Ghana Official (@_missghana) on Instagram: "Who's Your Queen To Be Irene Vanessa Vifah (3) #vote3 #voteirenevanessa *711*5..."
