A box contains 5 red, 6 green and 7 yellow pencils of the same size. What is the probability of picking a green pencil at random?
- \(\frac{1}{6}\)
- \(\frac{1}{4}\)
-
\(\frac{1}{3}\)
- \(\frac{1}{2}\)
The correct answer is: C
Explanation
Pr(green) = \(\frac{6}{5 + 6 + 7}\)
= \(\frac{6}{18}\)
= \(\frac{1}{3}\)
