    A)                 \[\frac{2}{7}\]       

    B)                 \[\frac{1}{7}\]

    C)                 \[\frac{3}{7}\]       

    D)                 None of these

    Correct Answer: B

    Solution :

                    In a non-leap year, we have 365 days i.e.,  52 weeks and one day. So, we may have any day of seven days. Therefore, 53 Sunday, required probability = \[\frac{1}{7}\].
