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). Web1. Suppose the joint pmf of X and Y isgiven byp(1,1) = 0.5, p(1,2) = 0.1, p(2,1) = 0.1, p(2,2) = 0.3. Find the pmf of X given Y = 1. Solution: pX Y=1(1) = p(1,1)/pY (1) = 0.5/0.6 = 5/6 pX Y=1(2) = p(2,1)/pY (1) = 0.1/0.6 = 1/6 2. If X and Y are independent Poisson RVs with respec-tive means λ1 and λ2, find the conditional pmf of X
Webp q (disjunction of p and q): the proposition “p or q,” which is true if and only if at least one of p and q is (1). p → q (p implies q): the proposition “if p, then q,” which is (2) if and only if p is true and q is false.
