A bag contains 18 balls out of which x balls are red.
(i) If one balls 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 of drawing a red ball will be ` 9/8` times the probabability of drawing a red ball in the first case. Find the value of x.
