Can someone smarter than me help figure this out, please?
Several years ago I drove for FedEx. Was in Harvard Square, Cambridge MA sitting in traffic when saw Dad, Mom and teenage girl walking past me. Daughter had very unusual shirt on (basically no back, just straps). Saw them like 5 times before made it thru the square. 5 hours later, I am on the other side of Cambridge, about 5 miles or so, when I see the same family walking.
How do you calculate the odds/probability/chances (don’t even know what to call it) that 1, I saw them in the first place (would it be 7 billion to 1? Or, just like 1000 to 1, the number of people in Harvard Square at the time?) and 2 that I saw them again hours and miles later? I mean, if I had been +/- 5 minutes I would have missed them both times. Don’t even know how to begin to figure it out. TY in advance!
