    A)  \[\frac{1}{6}\]                    

    B)         \[\frac{2}{3}\] 

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

    D)         \[\frac{1}{4}\]

    Correct Answer: A

    Solution :

     Each of the 6 marbles has an equal chance of being picked. So, the probability that the marble picked is 3 will be 1 out of 6 i.e. \[\frac{1}{6}.\]
