WebAs with one RV, the goal of introducing the joint pmf is to extract all the information in the probability measure P that is relevant to the RV’s we are considering. So we should be able to compute the probability of any event defined just in terms of the RV’s using only their joint pmf. Consider two RV’s X,Y. WebA certain joint probability density function is given by the formula f_ {XY} (xy) = \dfrac {\sqrt {\pi}} {2} x\sin (xy), f XY (xy) = 2πxsin(xy), where x x and y y are drawn from the rectangle \big [0,\sqrt {\pi}\big]\times \big [0,\sqrt {\pi}\big]. [0, π]×[0, π]. Are the random variables X X and Y Y independent?

WebJan 11, 2024 · For independent random variables X ∼ Exp (1) and Y ∼ Exp (2), find the density of (Z, W) = (X-2Y, X). My approach: Since for any exponential distribution with parameter λ the function is f ( x) = λ e − λ x. f X ( x) = e − x. f Y ( y) = 2 e − 2 y. Therefore the joint density function is: f X, Y ( x, y) = f X ( x) f Y ( y) = { 2 e ...
