- What is the probability of getting 53 Mondays in a leap year?
Question 1:
What is the probability of getting 53 Mondays in a leap year? A. 1/7
B. 53/366
C. 2/7
Feedback With 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)
i.e., there are 7 pairs, in which Monday occurs in 2 pairs,
So probability is:P (53 Monday) = 2/7
