Multiple choice

A bag contains 10 red balls and 7 blue balls. A ball is drawn at random. The probability that ball drawn is not red is

  1. $\dfrac{7}{10}$
  2. $\dfrac3{17}$
  3. $\dfrac{10}{17}$
  4. $\dfrac{7}{17}$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Total balls = 10 + 7 = 17. Probability of red = 10/17. Probability of not red = 1 - 10/17 = 7/17.

AI explanation

The total number of balls in the bag is 10 red plus 7 blue, which equals 17. The probability of drawing a ball that is not red is the number of blue balls divided by the total number of balls. Therefore, the required probability is 7 divided by 17.
