Hope this is the right sub forum for this topic.

Chatting with a work colleague yesterday and he shared that his parents who are still married are both over 100 years old. I’ve never encountered this and started thinking about the odds of this.

Based on 1% of the US population living to be over 100 I think that picking two people at random who both live to over 100 would be 1 in 10000. I have no idea how to then incorporate the fact the the two people are also married. Statistics isn’t my strong point! Does anyone have any thoughts on how to quantify how rare this is?
