C Correct answer
Explanation

Total balls = 15. Non-red balls = 5 blue + 3 green = 8. Probability = (8/15) * (7/14) = (8/15) * (1/2) = 4/15.

AI explanation

The total balls equal 15, and the non-red balls total 8. We must find the probability of drawing 2 non-red balls from the 8 available, calculated as 8C2 divided by the total ways to pick 2 balls, 15C2. This gives 28 divided by 105, which simplifies to 4/15.
