Practicing Success
A bag contains 5 black, 3 white and 2 red balls. Three balls are drawn in succession. What is the probability that the first ball is red, the second ball is black and the third ball is white? |
$\frac{1}{24}$ $\frac{3}{10}$ $\frac{1}{10}$ $\frac{1}{2}$ |
$\frac{1}{24}$ |
We have, A bag contains 5 black, 3 white and 2 red balls Total number of balls = 5 + 3 + 2 = 10 Among three balls the probability that the first ball is red, the second ball is black and the third ball is white = = \(\frac{5}{10}\) × \(\frac{3}{9}\) × \(\frac{2}{8}\) = $\frac{1}{24}$ |
