how to define event to javascript/jquery?

What would be your approach to define probability of incredible event happening (details follow) ?

• I've recently found a photo with pretty interesting history. A married couple was photographed at Disneyland 15 years before they got married, they then didn't know each other and even lived in different countries. So how one can try to estimate the probability of such event? What would you start from to define it? http://www.neatorama.com/2010/06/13/disney-photo-captured-married-couple-on-film-15-years-before-they-met/

• Answer:

  Richard Feynman used to go up to people all the time and he'd say "You won't believe  what happened to me today... you won't believe what happened to me" and  people would say "What?" and he'd say "Absolutely nothing". Because we  humans believe that everything that happens to us is special and  significant. If you think about all the variables:  the probability that the married couple being in the same place at the same time, coming from different countries,.... whatever. It's zero. Every event that happens has  a really small probability... but it happens... So the real thing that  physics tell us about the Universe (or our universe) is that it's big, rare events happens  all the time — e.g. life — and that doesn't mean it's special... Events with probability Zero are always occurring...
