Question

A bag contains 6 red, 8 black and 4 white balls. A ball is drawn at random, What is the probability that the ball drawn is not black?

• A. $\frac{5}{9}$
• B. $\frac{3}{4}$
• C. $\frac{1}{7}$
• D. $\frac{3}{7}$

Answer 1

The correct option is A $\frac{5}{9}$

Total number of balls = 18

Number of black balls = 8

Probability that ball is black $=\frac{8}{18}=\frac{4}{9}$

Probability that ball is not black $=1-\frac{4}{9}=\frac{5}{9}$
