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