A box contains 2 white stickers, 6 purple stickers, and 2 black stickers. If one sticker is chosen without looking, what is the probability that it is white?
- 2 white stickers
- 6 purple stickers
- 2 black 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 white stickers.
- Then count all possible outcomes: 2 + 6 + 2 = 10.
- Probability means favorable outcomes divided by total outcomes, so the probability is 2/10, which simplifies to 1/5.
The correct answer is 1/5. This matches the calculation or definition, so students should focus on the reasoning rather than only memorizing the final value.
