1.	Find the probability of having 53 Sundays in a year.
Answer» For solving this question we should know a basic fact about a year i.e. it has 52 weeks. 52 weeks means 52×7 = 364 days. If the year in an ordinary year, the one odd day could be Monday,Tuesday, Wednesday…… Sunday. Thus the probability of getting a sunday is1/7. If the year is a leap year, the two odd days could be Mon Tue, Tue Wed, Wed Thu , Thu Fri , Fri Sat , SatSun,SunMon. Thus the probability of getting a sunday is2/7
