This is what’s confusing and inherently untrue about statistics. And it’s unfortunate that our business and our country are run off such flawed statistics.
The odds of an individual being born on a given day is 1/365. Period. The fact that the parents also have the same birthdates has no effect whatsoever on this statistic.
If I were to wager on which date a child will be born I would look at it as a 1/365 chance irrespective of what his parents birthdates are. Also, the chances of being born on a particular hour is 1/24, irrespective of the hour his parents were born.
The chances of an individual winning a lottery ticket does NOT diminish just because they have previously won the lotto. Their chances are exactly the same!
So, I need to be convinced here of the legitimacy of these statistics.
