p.d.f is through an example. Example 11.1: Given $f_{XY}(x, y) = \begin{cases} k, & 0 < x < y < 1, \\ 0, & \text{otherwise} \end{cases}$ (11-16) determine $f_{X|Y}(x|y)$ and $f_{Y|X}(y|x)$. Solution: The joint p.d.f is given to be a constant in the shaded region. This gives $\iint f_{XY}(x, y)dxdy = \int_0^1 \int_0^y k dx dy = \int_0^1 ky dy = \frac{k}{2} = 1 \implies k = 2.$ Similarly $f_X(x) = \int f_{XY}(x, y)dy = \int_x^1 k dy = k(1-x), \quad 0 < x < 1,$ (11-17) and $f_Y(y) = \int f_{XY}(x, y)dx = \int_0^y k dx = ky, \quad 0 < y < 1.$ (11-18)
