A box contains 3 green cards, 8 orange cards, and 1 black cards. If one card is chosen without looking, what is the probability that it is orange?
- 3 green cards
- 8 orange cards
- 1 black cards
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 8 orange cards.
- Then count all possible outcomes: 3 + 8 + 1 = 12.
- Probability means favorable outcomes divided by total outcomes, so the probability is 8/12, which simplifies to 2/3.
The correct answer is 2/3. This matches the calculation or definition, so students should focus on the reasoning rather than only memorizing the final value.
