Question

A bag contains 5 black balls, 4 white balls and 3 red balls. If a ball is selected at random, the probability that it is not red is

Answer 1

Answer:

9/12

Step-by-step explanation:

total number of balls = 12

balls which are red = 3

therefore, at random, the probability of not picking red ball = 12/12 - 3/12= 9/12

Answer 2

total balls are 12

number of red balls is 3

probability that the ball is not red is 9/12

3/4
