Answer 1

Answer:

The question I am answering asks:

"What is the probability of getting 53 Sundays in a year?"

I believe the answer is 73/400 = 0.1825.

I note that nobody else got this answer so either I am wrong or all the other answers are wrong. Statistically, I realise the odds are not in my favour!

I will now give a brief explanation of how I arrived at this answer.

A non-leap year contains 365 days and 365 = (52 x 7) + 1. That means that for a non-leap year to contain 53 Sundays, 1 January must fall on a Sunday. A leap year contains 366 days = (52 x 7) + 2 days, so for a leap year to contain 53 Sundays, 1 January or 2 January must be a Sunday.

So the years which contain 53 Sundays are the years (leap or non-leap) in which 1 January falls on a Sunday plus the leap years in which 2 January is a Sunday (or 1 January is a Saturday).

Leap years are those years exactly divisible by 4, with the exception that years ending in 00 are only leap if they are divisible by 400. For example 2000 and 2400 are leap years but 1800, 1900 and 2100 are not.

So the pattern or cycle of the number of days in a year repeats or starts again after 400 years.

In any period of 400 years there are 97 leap years, so the nu
