A ball is drawn at random from a bag containing 1 black ball and 1 green ball. If the drawn ball is black then it is replaced in the bag and again a ball is drawn from the bag. But if the first drawn ball is green, then a die is rolled .Write down the sample space associated with this random experiment.
