Two electronic components of a missile system work in harmony for the success of the total system. Let X and Y denote the life in hours of the two com-ponents. The joint density of X and Y is
f(x,y) = {yc⁻ʸ⁽¹⁺ˣ⁾, x ≥ 0; y ≥ 0}
{0 otherwise}
a). Give the marginal density functions for both random variable
