1 year = 365 days A leap year has 366 days A year has 52 weeks. Hence there will be 52 Sundays for sure. 52 weeks = days 366 – 364 =2 days In a leap year there will be 52 Sundays and 2 days will be left. These 2 days can be: Sunday, Monday Monday, Tuesday Tuesday, Wednesday Wednesday, Thursday Thursday, Friday Friday, Saturday Saturday, Sunday Of these total 7 outcomes, the favourable outcomes are 2. Hence the probability of getting 53 days =2/3 Visit www.ethicalabhishek.tk for my website
