My 3 sons were born on 5/12, 5/31 and 7/17. Our good friends in Indianapolis have 3 daughters born on 5/12, 5/31 and 7/17.
Wow that's pretty cool!
In my family - All three of my grandma & grandpa's daughters were pregnant at the same time. All three had GIRLS in the month of March, 1974, THREE weeks apart! (I was born in the middle) ;) As you can imagine, we have lots of pictures and old home movies of us three as newborns all behing held (at the same time) by various family members. :)
Ladies and germs, hobos and tramps, wicked mosquitos and bowlegged ants...I come before you and stand behind you to tell you something which I know nothing about...
Next Thursday, which is good Friday, there's a seminar. Admission free, pay at the door, drag up a chair, sit on the floor...
In our family, three cousins share the same birthday, each birthday 12 years after the other.
I share a birthday with Ann Coulter!
Dec. 8.
She is older tho.
Well if you only have sex oned a year.
Well if you only have sex once a year.
Now to the numbers:
1. Assuming that impregnation is equally probable on any given month; and assuming normal variations in gestation time, one can reasonably assume that any given birthday on a given year is equally likely. (P=1/365.25)
2. Assume that impregnation is equally likely in any given year over the ~20 child-bearing years of the mother.
3. So the probability of having a birthday on any given day over that 20 years is 1/(365.25*20) = 1/7305.
4. Assuming that the births are statistically independent (perhaps not a good assumption), the probability of ANY four births occurring on specified dates is (1/7305)4 = ~1/315.
Note again that any specified combination of 4 birthdays is equally likely (or unlikely).
But talk about it twice, like you? ;o)

Apologies to Groucho.
bump for later
Say the secret woid and win a pair of flip-flops...

My sister and her son share her birthday(and her daughter 1 day before). My Mother shared her Mother's birthday. I share mine with George H.W. Bush.
This reminds me of a similar story in Anacostia, except they were all 13 years apart.
lol
My two sons were born on the same date three years apart. It's also their paternal grandfathers birthday.
Thank you very much for answering. 1/3000000000000000 sounds like a big ol' number to me! (But it probably isn't in the grand scheme of things...)
