A box contains 2 green tiles, 7 purple tiles, and 8 blue tiles. If one tile is chosen without looking, what is the probability that it is green?
- 2 green tiles
- 7 purple tiles
- 8 blue 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 green tiles.
- Then count all possible outcomes: 2 + 7 + 8 = 17.
- Probability means favorable outcomes divided by total outcomes, so the probability is 2/17, which simplifies to 2/17.
The correct answer is 2/17. This matches the calculation or definition, so students should focus on the reasoning rather than only memorizing the final value.
