Choose the best answer. If necessary, use the paper you were given.
A bowl contains 6 green grapes, 10 red grapes, and 8 black grapes.Which of the following is the correct calculation for the probability of choosing a red grape and then without putting the red grape back into the bowl, choosing a green grape?
Answer Choices
- A: 10/24+6/24
- B: 10/24+6/23
- C: 10/24*6/24
- D: 10/24*6/23
Correct Answer: D
Rationale: Probability (Red first) = 10/24. Probability (Green second | Red first) = 6/23 (since one grape is removed). Since "and" implies both events, multiply: (10/24) * (6/23).
