A box contains 3 purple counters, 2 orange counters, and 1 white counters. If one counter is chosen without looking, what is the probability that it is purple?
- 3 purple counters
- 2 orange counters
- 1 white 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 3 purple counters.
- Then count all possible outcomes: 3 + 2 + 1 = 6.
- Probability means favorable outcomes divided by total outcomes, so the probability is 3/6, which simplifies to 1/2.
The correct answer is 1/2. This matches the calculation or definition, so students should focus on the reasoning rather than only memorizing the final value.
