    Young Henry mentioned his mother's Birthday below and it reminded me of a probability experiment that states if 23 people are in a room, it is more likely than less that 2 of them share a birthday. What date is your birthday people? Mine is 31st March. Let us see if the first 23 posters to this can get a matching pair?

                    25th July, btw. And a quick head reckoning says that it's 39-40 people for an evens chance. Of course, it's 6.30 am, here, so my arithmetic might not be all that it can be.

                        I believe you are a bit wrong. If you have 366 people, you can guarantee that at least 2 people share birthdays. It´s called "the Pigeonhole principle" http://en.wikipedia.org/wiki/Pigeonhole_principle[^]

                                Actually, i think they share the same month, not the exact date. This is a theory of combinatorics (the pigeon hole principle) rather than probability. In any event: 13th February

                                      The way I know it: If you have 366 people in a room, it's guaranteed (100%) that at least 2 share their birthday, which is obvious. If you have 23 people in a room, it's likely (> 50%) that at least 2 share their birthday, which is not obvious, but it's mathematically proved to be true.

                                          Young Henry mentioned his mother's Birthday below and it reminded me of a probability experiment that states if 23 people are in a room, it is more likely than less that 2 of them share a birthday. What date is your birthday people? Mine is 31st March. Let us see if the first 23 posters to this can get a matching pair?
