A box contains 4 yellow beads, 6 green beads, and 8 purple beads. If one bead is chosen without looking, what is the probability that it is green?
- 4 yellow beads
- 6 green beads
- 8 purple beads
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 6 green beads.
- Then count all possible outcomes: 4 + 6 + 8 = 18.
- Probability means favorable outcomes divided by total outcomes, so the probability is 6/18, which simplifies to 1/3.
The correct answer is 1/3. This matches the calculation or definition, so students should focus on the reasoning rather than only memorizing the final value.
