Question :-

What is the probability that a leap year has 53 sundays?

Required Answer :-

A leap year has 366 days i.e. 52 weeks and 2 days.

Sample space for last two days :-

S = { (Sunday, Monday)

(Monday, Tuesday)

(Tuesday, Wednesday)

(Wednesday, Thursday)

(Thursday, Friday)

(Friday, Saturday)

(Saturday, Sunday)

n(S) = 7

Let A be the event of getting 53 sundays in a year.

A = { (Sunday, Monday) (saturday,sunday)}

n(A) = 2

P(A) = n(A)/n(S)

P(A) = 2/7

Therefore, probability of getting 53 sundays in a leap year is 2/7
