Question

What is the probability that a non leap year has 53 mondays?

Answer 1

Hello Dear!!!

A non leap year has 365 days.

There will be 52 weeks.

There are 7 days in a week.

52*7 = 364.

There are 52 Sundays in 52 weeks.

But... we got only 364 days..

Then what about the other day....

It may be Sunday,Monday,Tuesday, Wednesday, Thursday, Friday, Saturday.

So.. possible number of Sundays are 52+1

So...possible number of outcomes are 53.

Total number of outcomes are 365.

Probability = possible number of outcomes/total number of outcomes.

Probability = 53/365

Probability = 1/7.
