Question: 1.2.7 Let U and W be jointly distributed random variables. Show that U and W are independent if Pr{U>u and W>w} = Pr{U> u} Pr{W>

1.2.7 Let U and W be jointly distributed random variables. Show that U and W are independent if

Pr{U>u and W>w} = Pr{U> u} Pr{W> w} for all u, w.

Pr{U>u and W>w} = Pr{U> u} Pr{W> w} for all u, w.
