# A Bag Contains 4 White Balls, 5 Red Balls, 2 Black Balls and 4 Green Balls. a Ball is Drawn at Random from the Bag. Find the Probability that It is Not Green. - Mathematics

Short Note

A bag contains 4 white balls, 5 red balls, 2 black balls and 4 green balls. A ball is drawn at random from the bag. Find the probability that it is not green.

#### Solution

Total number of balls = 15

Number of balls which are not green = 4 + 5 + 2 = 11

∴  P(getting a ball which is not green) ="Number of  favourable outcomes "/"Number of all possible outcome"= 11/15

Thus, the probability of getting a ball which is not green is11/150.
