The joint distribution function of the variables X and Y is defined as F(x,y) =1-(1)/(y)-e^(-x)+(e^(-x))/(y) for all 0<=x and 1<=y and is zero everywhere else. What is F_(x)(x)?
Added by Patrick E.
Step 1
We are given the joint distribution function F(x,y) and we need to find the marginal distribution function F_X(x) of X. Show more…

Suppose that X and Y are jointly continuous with joint probability density function fX,Y(x,y) = { 2e^-(x+2y) if x > 0, y > 0 0 otherwise a. Sketch the support of joint distribution (X, Y). b. Show that X and Y are independent random variables and provide their marginal distributions.
