    A bag contains 4 red, 5 black and 3 yellow balls. A ball is taken out of the bag at random. Find the probability that the ball taken out is not of yellow colour.

    A) \[\frac{2}{3}\]

    B) \[\frac{1}{3}\]

    C) \[\frac{3}{4}\]

    D) \[\frac{1}{2}\]

    Correct Answer: C

    Solution :

    [c] Total number of possible outcomes \[=\text{4}+\text{5}+\text{3}=\text{12}\]
    Favourable number of outcomes \[~=\text{5}+\text{4}=\text{9}\]
    \[\therefore \] Required probability \[=\frac{9}{12}=\frac{3}{4}\]
