If the independent random variables X and Y have the mariginal densities

f(x)= 0.5 for 0<x<2 and zero elsewhere

g(y)=1/3 for 0<y<3 and zero elsewhere

find the value of P(X^2+Y^2 > 1)

I have the joint prob. density h(x,y)=1/6 for 0<x<2, 0<y<3 and zero elsewhere, it's because they are independent, so their joint p density is the product of those two. and don't know what to do next...

And I thank you all in advance, "Thank you"
