Question

A bag contains 5 red balls and 8 blue balls. It also contains 4 green and 7 black balls. If a ball is drawn at random, find the probability that it is not green.

• A. $\frac{5}{6}$
• B. $\frac{1}{4}$
• C. $\frac{1}{6}$
• D. $\frac{7}{4}$

Answer 1

The correct option is A $\frac{5}{6}$

Total Number of Balls $=5+8+4+7=24$ balls

Probability of not getting a green ball $=\frac{5+8+7}{24}=\frac{5}{6}$
