B Correct answer
Explanation

Total balls = 3 + 4 + 5 = 12. Red or green balls = 3 + 5 = 8. Probability = 8 / 12 = 2 / 3.

AI explanation

There are 3 plus 4 plus 5, which is 12 total balls. The number of balls that are either red or green is 3 plus 5, which is 8. The probability of drawing a red or green ball is 8 divided by 12, which simplifies to 2 divided by 3.
