What is the probability of getting 53 Mondays in a leap year?

Answers (1)

Leap year has 366 days, the number of weeks in a year is

366/7 = 52 (2/7)

i.e., 52 complete weeks which contains 52 Mondays,

Now 2 days of the year are remaining.

These two days can be

(Sunday, Monday), (Monday, Tuesday), (Tuesday, Wednesday), (Wednesday, Thursday), (Thursday, Friday), (Friday, Saturday), (Saturday, Sunday)

There are 7 pairs, in which Monday occurs in 2 pairs,

So the probability is:

P (53 Monday) = 2/7
