WebThe joint probability mass function of (X, Y) is given by p(x, y) = k(2x + 3y), x = 0, 1, 2; y = 1, 2, 3. Find all the marginal and conditional probability distributions. Also find the probability d Web(1−p)n−1p = (1−p)i−1. (1) So, we obtain P[X = Y] = pq p+q −pq (b) What is E[max(X,Y)]? We know from problem MU 2.9 that E[max(X,Y)] = E[X] + E[Y] − E[min(X,Y)]. From below, in part (c), we know that min(X,Y) is a geometric random variable mean p+q −pq. Therefore, E[min(X,Y)] = 1 p+q−pq, and we get E[max(X,Y)] = 1 p + 1 q − 1 p ...

WebLets see it a bit. We have given that: f ( x, y) = { x y if 0 ≤ x ≤ 2 and 0 ≤ y ≤ 1 , 0 else. So, I have to find this probability P ( X / 2 < Y < X) To begin with, I found f, y. f x ( x) = x / 2 and f y ( y) = 2 y. So as you can see f x and f y are independent as f x ⋅ f y = f ( x, y). WebP x,y f X,Y (x,y) = 1. The distribution of an individual random variable is call the marginal distribution. The marginal mass function for X is found by summing over the appropriate column and the marginal mass function rob roy reservoir fire
