A box contains 2 purple stickers, 4 blue stickers, and 7 yellow stickers. If one sticker is chosen without looking, what is the probability that it is purple?
- 2 purple stickers
- 4 blue stickers
- 7 yellow stickers
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 purple stickers.
- Then count all possible outcomes: 2 + 4 + 7 = 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.
