        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?

              This is just basic probability. One of my favourite maths experiments is to ask people whether or not they are more likely to roll two consecutive 6s with a dice or a 2 then a 3.

                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[^]

                    The probability of at least two people sharing the same birthday is 0.5073. Yay, I've found a use for Wolfram Alpha! http://www04.wolframalpha.com/input/?i=same+birthday&f1=23&f=BirthdayProblem.n_23&x=5&y=9[^]
