Ok, statistics question

Littlejen22

My kids were born on the same day.  Everyone keeps saying, "what are the odds."  Not that they really want an answer to that but is it 1 in 365 (the chance that DD would be born on December 12 since DS was already born on that day) or 1 in 730 (the chance they would both be born on December 12)?  DH and I disagree on this.  Man, and I took statistics in undergrad and in a Masters program...I hated it, lol.

I don't know but that is something else.  I love it.

II think it's more complicated than that.  Unless you conceived on the same day then I think it would be 1 in 365.

This is the closest I could find.

Well if it's 1 in 365 for each kid you multiple (1/365)*(1/365) and that becomes a very small number.

But I remember reading an article why it's actually really common to have a kid in your class with the same birthday....

This is what I was about to post. I think you should try for another child and see if you can hit the jackpot with another child with that birthday.

Lol, I think I would be committed after losing my mind if I had another one on the same day - I was so upset, mostly for DS, that I went into labor on his birthday...not depressed but you get what I mean.  I will have to find a way to convince them how special it is and really hope they are very close to each other.  I will now read the link.
