Question

Find the probability that a leap year has 53 fridays

Answer 1

A leap year has 52 complete weeks plus 2 days. Hence if the leap yearbegins on a Sunday, it will have 53Sundays and Mondays and 52 other days of the week. Thus a leap year willhave 53 Fridays if the year begins on a Thursday or Friday. The probability that a leap year begins on any day of the year is the same = 1/7.
