10.4 Exercise 10

Avg difficulty 2.5

For the pair {X,Y}\left\{X , Y\right\} in the exercise, let

W = g ( X , Y ) = X for X + Y ≤ 4 2 Y for X + Y > 4 = I M ( X , Y ) X + I M c ( X , Y ) 2 Y W = g \left(X , Y\right) = \left\{\begin{matrix} X & \text{for} X + Y \leq 4 \\ 2 Y & \text{for} X + Y > 4 \end{matrix}\right = I_{M} \left(X , Y\right) X + I_{M^{c}} \left(X , Y\right) 2 Y

Determine and plot the distribution function for W.
