A bag contains 18 balls out o f which x balls are red.
(I)If one ball Is drawn at random from the bag, what Is the probability that It Is not red?
(II) If two more red balls are put In the bag, the probability o f drawing a red ball w ill be | times the probability o f drawing a red ball In the firs t case. Find the value o f x.
