    Solution

    A non-leap year has 365 days, which means: It has 52 full weeks (each week has 7 days). 1 extra day is left (it can be any of the 7 days: Sunday, Monday, Tuesday, etc.). For there to be 53 Sundays, this extra day must be Sunday. Since the extra day can be any one of 7 days, the probability is = 1/7
