Question

In a bag, there are 5 red, 7 white and 3 green balls. One ball is taken out randomly.  What is the probability that the ball is neither white nor green?

1. 1/9
2. 1/3
3. 1/7
4. 1/10
5. 1/5

Answer 1

Correct Answer - Option 2 : 1/3

Given:

Number of green ball = 3

Number of white balls = 7

Number of red balls = 5

Calculation:

Total number of balls = (5 + 7 + 3) = 15

Number of red balls = 5

∴ Probability that the ball is neither white nor green = 5/15 = 1/3
