A box contains 2 white balls,1 black ball, 2 red balls, and a green ball. 2 Balls are taken randomly from the box. What is the probability that 2 balls are white?
Given :
A box contains 2 white balls,1 black ball, 2 red balls, and a green ball.
Two balls are taken randomly from the box.
To do :
We have to find the probability of getting two white balls.
Solution :
Number of white balls $=2$
Total number of balls $= 2+1+2+1=6$
Probability of getting 2 white balls $= \frac{Number of white balls}{Tota number of balls}$
$= \frac{2}{6}$
$=\frac{1}{3}$
Therefore, the probability of getting white balls is $\frac{1}{3}$.
