Question

A bag contains 3 white, 4 black, 2 red balls. If 2 balls are drawn at random, then the probability that both the balls are white, is (A) (1/18) (B) (1/36) (C) (1/12) (D) (1/24)

Total number of balls = 9 Probability of drawn two white balls = (3/9) × (2/8) = (1/12)

Q. A bag contains $3$ white, $4$ black, $2$ red balls. If $2$ balls are drawn at random, then the probability that both the balls are white, is

$\frac{1}{18}$

$\frac{1}{36}$

$\frac{1}{12}$

$\frac{1}{24}$

Total number of balls = 9
Probability of drawn two white balls
$= \frac{3}{9} \times \frac{2}{8} = \frac{1}{12}$
