Discussion
A bucket contains 10 brown balls, 8 green balls, and 12 red balls and you pick one randomly without looking. What is the probability that the ball will be brown?
Answer: C
The bucket holds \( 10 + 8 + 12 = 30 \) balls.
\[ P = \frac{10}{30} = \frac{1}{3} \]
The decimal 0.33 is only an approximation of \( \tfrac{1}{3} \), which is the exact value.
