    B)  \[\frac{3}{13}\]

    C)  \[\frac{4}{13}\]                                 

    D)  \[\frac{2}{13}\]

    E)  Other than the given options

    Correct Answer: A

    Solution :

     Required probability \[=\frac{^{7}{{C}_{3}}}{^{15}{{C}_{3}}}=\frac{7\times 6\times 5}{15\times 14\times 13}=\frac{1}{13}\]
