A box contains 6 black tokens, 4 red tokens, and 5 orange tokens. If one token is chosen without looking, what is the probability that it is black?
- 6 black tokens
- 4 red tokens
- 5 orange tokens
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 6 black tokens.
- Then count all possible outcomes: 6 + 4 + 5 = 15.
- Probability means favorable outcomes divided by total outcomes, so the probability is 6/15, which simplifies to 2/5.
The correct answer is 2/5. This matches the calculation or definition, so students should focus on the reasoning rather than only memorizing the final value.
