Explanation

Total balls = 5+9+6 = 20. Neither red nor green means black. Number of black balls = 6. Probability = 6/20.

AI explanation

The box contains 5 red, 9 green, and 6 black balls, giving a total of 20 balls. The probability of selecting a ball that is neither red nor green is the same as the probability of selecting a black ball. Using the classical probability formula, this is 6/20.
