MCQ

A bag contains 3 white, 4 red and 5 black balls. One ball is drawn at random. What is the probability that the ball drawn is neither black nor white?

• 1/4

• 1/2

• 1/3

• 3/4

#### Solution

1/3

Explanation:

Total possible outcomes = Total number of balls = ( 3 + 4 + 5) = 12

Total number of balls that are non-black and non-white  = 4

∴ P (getting a ball that is neither black nor white)  = 4/12 = 1/3

Is there an error in this question or solution?
