A Correct answer
Explanation

Total number of balls = 4 red + 6 blue + 7 yellow = 17. The number of balls that are not blue is 4 red + 7 yellow = 11. The probability of selecting a non-blue ball is 11/17.

AI explanation

The total number of balls in the bag is the sum of the different colors, which is 4 + 6 + 7 = 17. The number of balls that are not blue is the sum of red and yellow balls, which is 4 + 7 = 11. The probability of selecting a non-blue ball is the number of non-blue balls divided by the total balls, giving 11/17. The result is 11/17.
