Since there are total 52 weeks (364 days) and 2 days (total 366 days) in a leap year, their will definitely be 52 Sundays, so now we should check the last two days.

The possible combinations are :

(Monday,Tuesday),(Tuesday,Wednesday),(Wednesday,Thursday),(Thursday,Friday),(Friday,Saturday),(Saturday,Sunday),(Sunday,Monday).

Out of these 7 possible combinations last 2 have Sundays. So required probability = 2/7=0.285
