Well, I at least slept a couple of hours.
Thanks for the data analysis. It's not as lop-sided toward girls as I would have suspected. For some reason I always seem to read more posts about girls than boys as I'm reading the various threads/forums.
You can have an odd number and still not have anyone get their own name... A gets B, B gets C, C gets A...each gets someone but not their own. As long as one name goes in and one comes out, it should be a one-to-one correspondence. I think when you are thinking of an even match-up you are thinking of pairing off. Since you generally don't get the person who gets your name (although that is a possibility), this won't work in the same way.
I was interested in seeing the probability of getting a girl's name vs. a boy's. It's really too close to predict since there's a 57% chance of getting a female and a 43% chance of getting a male. It is more probable that the SB will be a female but not convincingly. Math doesn't seem to help too much in a case like this!
Hmmmm...so again we wait...LOL |
