Question

A bag contains 9 red and 6 blue balls. Find the probability that a ball d​rawn from a bag at random is red ball.

• A. $\frac{6}{15}$
• B. $\frac{3}{5}$
• C. $\frac{15}{15}$
• D. $1$

Answer 1

The correct option is B $\frac{3}{5}$

Total number of balls in bag = 15

Number of red balls = 9

Probability of getting a red ball = $\frac{\text{Number of red balls}}{\text{Total number of balls in bag}}$

$=\frac{9}{15}$ = $=\frac{3}{5}$
