Question

A bag contains 5 red , 4 green and 3 blue balls. If a ball is drawn at random, what is the probability of getting a red ball

• A. 1
• B. $\frac{5}{12}$
• C. $\frac{1}{3}$
• D. $\frac{1}{4}$

Answer 1

The correct option is B

$\frac{5}{12}$

Total number of balls in the bag = 5 + 4 + 3 = 12

Number of red ball = 5

$\therefore$ The probability of getting a red ball = $\frac{\text{number of favourable outcomes}}{\text{total number of outcomes}}$ = $\frac{5}{12}$
