    Joint Density

    Suppose X and Y are random variables whose joint density function is

    f(x, y) =o.3x^2+0.3y^2 and 0 otherwise.

    0<x<2, 0<y<1

    What is P[X^2 + Y^2 > 1]?

    draw and integrate
    most likely use polar and use the complementary region which is inside the circle

    I thought the region is between the circle and their range.
