Question

the probability that a leap year has 52 wensdays is

Answer 1

I think it's 1/7.............

Answer 2

There are 366 days in a leap year.

The number of weeks in a leap year = 7.

= 365/7

$= 52 \frac{2}{7}$

That means 52 weeks + 2 days.

These 2-days can be:

{Mon, Tues},{Tues, Wed},{Wed, Thurs},{Thurs, Fri},{Fri, Sat}, {Sat, Sun},{Sun, Mon}. = 7.

In order to have 53 Wednesdays, we should have either {Tues, Wed},{Wed, Thurs} = 2.


The probability that a leap year consists of 53 Wednesdays = 2/7.


The probability that a leap year consists of 52 Wednesdays = 1 - 2/7

                                                                                                     = 5/7.


Hope this helps!
