Given: A bag contains 6 red, 8 black and 4 white balls and a ball is drawn at random
Required to find: Probability that the ball drawn is not black
Total number of balls 6 + 8 + 4 = 18
Total number of black balls is 8
So, the total number of balls which are not black is 18 – 8 = 10
We know that, Probability = Number of favourable outcomes/ Total number of outcomes
Thus, the probability of drawing a ball which is not black = 10/18 = 5/9
