Correct Answer - Option 1 : 2/7
A leap year has 366 days or 52 weeks and 2 odd days.
The two odd days can be (Saturday,Sunday), (Sunday,Monday), (Monday,Tuesday), (Tuesday,Wednesday), (Wednesday,Thursday), (Thursday,Friday),(Friday,Saturday).
So there are 7 possibilities out of which 2 have a Saturday.
So the probability of 53 Saturday is 2/7.
Hence, the correct answer is 2/7.
