Hey there, I have a homework question for probability class...Here's the question:
f(x,y) = (1/210)(2x + y)
x --> (2, 6)
y --> (0, 5)
He wants us to find E (x), E(y), E(xy), E(x^2), E(y^2) and var(x)....where do I begin???
I know I'm supposed to set up some integral like this:
E(x) = (1/210) ∫ ∫x (2x + y) dxdy = 268/63 but then I get lost..
help please??
