Question

find probability of getting 53sundays in a leap year

Answer 1

The probability of a year being a leap year is 1/4

A leap year has 366 days or 52 weeks and 2 odd days.

The two odd days can be {Sunday,Monday},{Monday,Tuesday},{Tuesday,Wednesday}, Wednesday,Thursday},{Thursday,Friday},{Friday,Saturday},{Saturday,Sunday}.

So there are 7 possibiliyies out of which 2 have a Sunday.

So the probability of 53 Sundays in a leap year is 2/7.
