Hi guys, I have a question that I was talking about with someone a little while ago. The question is as follows:
If you have 4 people, what is the chances that 2 of them share the same birthday as well as the other 2 sharing a different birthday.
1st Jan, 1st Jan, 3rd May, 3rd May
or 2nd of March, 20th of December, 2nd of March, 20th December
All people being on the same born on the same day does not count.
