What are the odds of a mother giving birth to 3 children on 3 consecutive days, different years? Example: June 7, 1960, June 8, 1964, June 9, 1968 These were all natural births, no induced deliveries.

    That needs some pretty specific assumptions about the probability distribution of the time between two consecutive births. Lots of explicit choice on the part of the parents go into the calculation too.2012-06-02

    If those are all C-sections then the probability is pretty good.2012-06-02

    The question cannot be answered without knowledge of a vast array of real world data. Is an average baby equally likely to be born on any given day of the year? How many mothers have three children at all?2012-06-02

    Perhaps her husband worked was a sailor and came visit home the first days of every september...? things like these can affect probability in a serious way.2012-06-03
