1.	Find the probability that a non-leap year cotains 53 Thursdays.
Answer» A non-leap year has 365 daysA year has 52 weeks. Hence there will be 52 thrusday for sure.52 weeks = 52 x 7 = 364 days .365– 364 = 1day extra.In a non-leap year there will be 52 Thursday and 1day will be left.This 1 day can beSunday, Monday,Tuesday, Wednesday, Thursday,friday,Saturday, Sunday.Of these total 7 outcomes, the favourable outcomes are 1.Hence the probability of getting 53 Thursday= 1 / 7.∴ probability of getting 52 Thursday = 1 - 1/ 7 = 6 / 7.
