A box contains 3 red tiles, 3 blue tiles, and 8 white tiles. If one tile is chosen without looking, what is the probability that it is red?
- 3 red tiles
- 3 blue tiles
- 8 white 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 3 red tiles.
- Then count all possible outcomes: 3 + 3 + 8 = 14.
- Probability means favorable outcomes divided by total outcomes, so the probability is 3/14, which simplifies to 3/14.
The correct answer is 3/14. This matches the calculation or definition, so students should focus on the reasoning rather than only memorizing the final value.
