What is the likelihood that a leap year contains 53 Sundays and 52 Mondays?

Explanation

A leap year consists of 52 full weeks plus 2 extra days. There are 7 possible pairs of these extra days. Only one of these pairs includes a Sunday but not an extra Monday, resulting in 53 Sundays and 52 Mondays. Therefore, the probability is 1 out of 7.
