Solution

A bag contains one white ball (W) and one red ball (R).
When one ball is drawn, it will be either or R.
The sample space of drawing one white ball with replacement and then again drawing a ball is {(W, W), (W, R)}.
Again, if red ball is drawn, a dice is rolled.
The sample space associated with this experiment is given by {(R, 1)(R, 2)(R, 3)(R, 4)(R, 5)(R, 6)}.
Hence, the sample space S for this experiment is S = {(W, W)(W, R)(R, 1)(R, 2)(R, 3)(R, 4)(R, 5)(R, 6)}.
