A bag contains 18 balls out of 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 2 more red balls are put in the bag, the probability of drawing a red ball will be 98 times the probability of drawing a red ball in the first case. Find the value of x.

Answer:
1. 18 - x / 18.
Step-by-step explanation:
1. No of total balls = 18
No. Of red balls = x
No of balls not in red colour = 18 - x
Probility = no of non red balls / total no of balls.
Thus.... Ans = 18 - x / 18...
Hope it helps you..
