## Homework Statement

I have been given a joint PDF for X and Y, with ranges Y>X≥0.

I need to find the E(x) and E(y).

## Homework Equations

I know E(x) = ∫(x)*(f(x,y) dx and E(y) = ∫(y)*(f(x,y)) dy

## The Attempt at a Solution

For ∫x*f(x,y) dx, i used the limits = x to ∞

For ∫y*f(x,y) dy, i used the limits = 0 to y

Is this correct?
