Question

A bag contains one white and one red ball. A ball is drawn from the bag. If the ball drawn is white it is replaced in the bag and again a ball is drawn. Otherwise, a die is tossed. Write the sample space for this experiment.

Answer

A bag contains one white ball (W) and one red ball (R). When one ball is drawn, it will be either W 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)}.
