As there are 52 weeks in a year. 52 weeks correspond to 7*52=364 days. So, the last day is the one which should be a Sunday for you to get 53 Sundays. Sample space has seven days as options. So probability of getting 53 Sundays in a non-leap year is 1/7

A non leap year has 365 days. There are 52 weeks each having 7 days. This amounts to 52 x 7 = 364 days. The remaining 1 day can be any day among Monday, Tuesday,..., Sunday. Hence the required probability is 1/7.

Divide 365 by 7, we get 1 remainder. 365 days has 52 weeks and a extra day which can be any day among mon,tue,wed....sun. So 53rd sunday probability=1/7.

52 weeks*7 days per week = 364 days The remaining day in case of a non leap year is 1 (365-364) The possibilities of this day are Sun, Mon, Tue, Wed, Thu, Fri, Sat = 7 The favorable outcome = Sun = 1 Therefore the probability of getting 53 sundays in a non leap year = 1/7
