What is the probability of getting 53 Sundays in a 'Leap' year?
Select an option to attempt
Correct Answer: Option D
Explanation
A leap year has 366 days = 52 complete weeks (364 days) + 2 extra days. These 2 extra days can be any consecutive pair from the 7 possible pairs: {Mon-Tue, Tue-Wed, Wed-Thu, Thu-Fri, Fri-Sat, Sat-Sun, Sun-Mon}. For there to be 53 Sundays, Sunday must appear in the extra 2 days. Pairs containing Sunday: {Sat-Sun} and {Sun-Mon} → 2 favourable outcomes.
