A box contains 3 blue cards, 8 orange cards, and 5 purple cards. If one card is chosen without looking, what is the probability that it is orange?
- 3 blue cards
- 8 orange cards
- 5 purple 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 + 5 = 16.
- Probability means favorable outcomes divided by total outcomes, so the probability is 8/16, which simplifies to 1/2.
The correct answer is 1/2. This matches the calculation or definition, so students should focus on the reasoning rather than only memorizing the final value.
