Multiple choice

A bag contains 12 red balls and 10 blue balls. A ball is drawn at random. The probability that ball drawn is red is

  1. $\dfrac{1}{11}$
  2. $\dfrac{6}{11}$
  3. $\dfrac{5}{6}$

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Total balls = 12 + 10 = 22. Probability of red = 12 / 22 = 6 / 11.

AI explanation

The total number of balls is the sum of 12 red balls and 10 blue balls, which gives 22 balls. The probability of drawing a red ball is calculated by dividing the number of red balls by the total number of balls. Thus, the probability is 12 divided by 22, which simplifies to 6/11.
