BIRTHDAY PROBLEM

It is said that in a group of 23 randomly chosen people, there's a more than 50% chance that 2 people will have the same birthday. In a group of 57 people, the chance increases to 99%.

For this to be random, it's important that you just scroll to the bottom and add your birthday without looking at the others. When you have added your birthday, then you can check if anyone has the same birthday as yours.

I once had a class of 40 students, three of whom shared a birthday.

I'll start us off with December 1.

I once proposed this to a math class (of 25) and they looked at me like I was crazy. It had slipped my mind that the class had two sets of twins in it.

Wot-a-Lot
of babies born in May....
Is that because many people are on holiday in August????
Or is it just too hot to do anything else - in mid-Summer????

Please ask your parents, and get back to us....Thank you....

26 birthdate responses, and no twinning yet even though we've hit May rather heavily. But of course the maths told us that there'd only be a 50% chance. The 99% chance comes later.

Bingo! We made it with a couple extra!

This thread should now be closed, and someone can start a new one with people who have not yet responded.

We had twinning on the 28th date, and then again on 29th. The next twinning happened on 40th.

I'll start the count again with new birthdays starting now and see if we can get the first twinning on less than the 28th entry.

I just read Birthday Problem 2 which was closed on the second move. I don't think we can ever beat that.

Case is closed.
