Question 13

A box contains 3 blue, 2 white and 4 red marbles. If a marble is drawn at random from the box, what is the probability that it would be white.

Solution

Total number of marbles in the box = 3+2+4 = 9.
Total number of white marbles = 2
Hence, Probability of getting a white marble = $$\dfrac{2_{C_1}}{9_{C_1}} = \dfrac{2}{9}$$
