A box contains 2 orange counters, 2 purple counters, and 6 green counters. If one counter is chosen without looking, what is the probability that it is orange?
- 2 orange counters
- 2 purple counters
- 6 green counters
Choose the best answer.
Note
For basic probability, compare the number of favorable outcomes with the total number of equally likely outcomes.
- Count the favorable outcomes first: there are 2 orange counters.
- Then count all possible outcomes: 2 + 2 + 6 = 10.
- Probability means favorable outcomes divided by total outcomes, so the probability is 2/10, which simplifies to 1/5.
The correct answer is 1/5. This matches the calculation or definition, so students should focus on the reasoning rather than only memorizing the final value.
