A Correct answer
Explanation

There are 5 + 7 + 4 + 6 = 22 balls in total. Six are red, so the probability of drawing a red ball is 6/22 = 3/11.

AI explanation

The total number of balls is 22, calculated as 5 plus 7 plus 4 plus 6. Using the classical probability formula, the probability of drawing a red ball is the 6 red balls divided by the 22 total balls, which simplifies to 3/11.
