    If A and B are two events such that \[A\subseteq B,\]then \[p\left( \frac{B}{A} \right)\]is equal to:

    A)  0                                            

    B)  \[1\]                    

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

    D)         \[\frac{1}{3}\]

    Correct Answer: B

    Solution :

    If \[A\subseteq B,\]then \[P(A\cap B)=P(A)\] Now,     \[P\left( \frac{B}{A} \right)=\frac{P(B\cap A)}{P(A)}\]                 \[=\frac{P(A)}{P(A)}=1\]
