Question

A bag contains 8 red, 6 white and 4 black balls. A ball is drawn at random from the bag. Find the probability that the drawn ball is
(i) red or white
(ii) not black
(iii) neither white or black

Answer 1

(i) probability of a red or white ball = 7/9

(ii) probability of non-black ball = 7/9

(iii) probability of neither white nor black =  4/9

Step-by-step explanation:

A bag contains 8 red, 6 white and 4 black balls.

Total outcomes = 8 + 6 + 4 = 18

(i) probability of a red or white ball = 14/18 = 7/9

(ii) probability of non-black ball = 14/18 = 7/9

(iii) probability of neither white nor black = 8/18 = 4/9
