The amount of hamburgers (X) and hotdogs (Y) in pounds that a man eats at a picnic is given by the following distribution:

f(x,y)=2x2+y2 for0<x<1 and 0<y<1 f(x,y)=2x2+y2 for 0<x<1 and 0<y<1

What is the variance of the amount of hamburgers eaten using the marginal distribution for hamburgers?

x and y are squared
