(Bag Q contains 10 marbles of which 2 are red (R) and 8 are black (B). Bag S contains 12 marbles of which 4 are red (R), 2 are black (B) and 6 are green (G). A ball is drawn at random from bag Q and put into bag S. Then one ball drawn from bag S. Suppose R is a random variable of red ball was drawn from bag S.) 1. Random variable R can be A. (1, 2, 3) B.
