Question

What is the chance that leap year should have fifty three Sundays?

Answer 1

In 52 weeks

We have 52 Sundays.

We have to find the probability of getting one Sunday to form the remaining 2 days can be a combination of the following S = {Saturday to Sunday, Sunday to Monday, Monday, to Tuesday, Tuesday to wednes¬day, Wednesday to Thursday, Thursday to Friday, Friday and Saturday}.

(i.e) n(s) =7

In this = A{Saturday to Sunday, Sunday to Monday}

(i.e) n(A) = 2

So, P(A) = `2/7`
