Correct choice: C

Explanation:

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 = 52 x 7 = 364days 366 – 364 = 2 days In a leap year there will be 52 Sundays and 2 days will be left. These 2 days can be: 1. Sunday, Monday 2. Monday, Tuesday 3. Tuesday, Wednesday 4. Wednesday, Thursday 5. Thursday, Friday 6. Friday, Saturday 7. Saturday, Sunday Of these total 7 outcomes, the favourable outcomes are 2. Hence the probability of getting 53 days = 2/7
