How's that for coincidence? To one up myself, I know two people with the April First birthday, and they're the same age and opposite gender. Math is not convoluted, twisted, or other wise trying to control us. These seemingly counter-intuitive properties found in math seem counter to intuition only because common intuition is flawed.

No one cares. (my comment is purely caring about you, not your comments. I think the appropriate way to finish this up in a way that you understand is "ahahahahaha" and "Burn, Pregnant Dog"). My birthday falls on the 19th of September and I actually know someone in my own town that has the same birthday. Guess we beat the odds... sradz113, I hate to point it out to you but there is absolutely no point to both of your comments. No one cares. (my comment is purely caring about you, not your comments.

An odd multiple of five is an even multiple of five plus another five, which is therefore a multiple of 10 plus another 5. Multiples of 10 end in a 0, and adding the extra 5 gives the last digit as 5!"[/quote] wow there was absolutely no point to the 2nd half of that, it's like u decided to just keep saying stuff to sound intelligent instead of just saying 5x another odd number ends in 5 and leaving it at that ahahahaha...and as for Brett, b4 ur post i found at least 3 ppl in may and u said not a single person was in may. burn. aaand the reason i found this was bc someone had a stupid facebook app that said 6% of the world had her birthday and i decided it was simply not true and I have been looking into it since.

The probability of duplication is a whole lot more important when applied to real-life situations. For example, what is the probability of two DNA sequences to be identical, when N persons are considered? There is now software to calculate a wide variety of duplication cases or collisions, including the Birthday Paradox. This is the best material on duplication, birthday paradox – software is also available: http://saliu.com/birthday.html (The Birthday Paradox: Combinatorics, Probability of Duplication, Coincidences, Collisions, Lottery, Roulette, Social Security Number (SSN), Genetic Code, DNA).

Allan, can you confirm from the registrations, if it is not too private to share, do we have more men here than women ? May 14th is my B’day,
Going a bit off the topic,

I see a lot more men on Damninteresting than there are female (going by Screen names atleast) , in a bit of sexist comment :- Does this mean that men have more Graymatter than females , or perhaps they are the ones with more internet access and a tendency to laze time away on the internet.

Allan, can you confirm from the registrations, if it is not too private to share, do we have more men here than women ?
