A box contains 5 black tiles, 2 orange tiles, and 6 red tiles. If one tile is chosen without looking, what is the probability that it is orange?
- 5 black tiles
- 2 orange tiles
- 6 red tiles
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 tiles.
- Then count all possible outcomes: 5 + 2 + 6 = 13.
- Probability means favorable outcomes divided by total outcomes, so the probability is 2/13, which simplifies to 2/13.
The correct answer is 2/13. This matches the calculation or definition, so students should focus on the reasoning rather than only memorizing the final value.
