A box contains 4 red, 5 blue, and 6 green balls. If one ball is drawn at random, what is the probability that it is not blue?

1. 4/15
2. 9/15
3. 10/15
4. 6/15

Correct answer: 10/15

Solution

Total balls = 4 + 5 + 6 = 15. Balls that are not blue = 4 + 6 = 10. So the probability is $\frac{10}{15}$.
