A box contains 5 orange tiles, 2 red tiles, and 2 white tiles. If one tile is chosen without looking, what is the probability that it is red?
- 5 orange tiles
- 2 red tiles
- 2 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 2 red tiles.
- Then count all possible outcomes: 5 + 2 + 2 = 9.
- Probability means favorable outcomes divided by total outcomes, so the probability is 2/9, which simplifies to 2/9.
The correct answer is 2/9. This matches the calculation or definition, so students should focus on the reasoning rather than only memorizing the final value.
