B Correct answer
Explanation

The total number of balls is 2 + 3 + 5 = 10. The probability of drawing a red ball is the number of red balls divided by the total number of balls, which is 2/10.

AI explanation

The total number of balls in the bag is the sum of red, blue and green balls, which equals 2 plus 3 plus 5 to give 10 balls. The probability of an event is the number of favorable outcomes divided by the total number of possible outcomes. Since there are 2 red balls, the required probability is 2 divided by 10, which is 2/10.
