A box contains 3 blue beads, 7 red beads, and 6 yellow beads. If one bead is chosen without looking, what is the probability that it is yellow?
- 3 blue beads
- 7 red beads
- 6 yellow 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 yellow beads.
- Then count all possible outcomes: 3 + 7 + 6 = 16.
- Probability means favorable outcomes divided by total outcomes, so the probability is 6/16, which simplifies to 3/8.
The correct answer is 3/8. This matches the calculation or definition, so students should focus on the reasoning rather than only memorizing the final value.
