Question

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

• A. $\frac{1}{11}$
• B. $\frac{6}{11}$
• C. $\frac{5}{6}$
• D. None of these

Answer 1

The correct option is B $\frac{6}{11}$

Total Red balls: $12$

Total blue balls: $10$

Total Balls: $10+12=22$

Probability of ball drawn is a red ball:

$P\left(Red\right)=\frac{12}{22}=\frac{6}{11}$
