In practice, when people say “one in a million” in that kind of context, it’s much higher than that. I haven’t watched Dumb and Dumber, but I’d be surprised if Lloyd did not, actually, have a decent chance of ending together with Mary.
On one hand, we claim [dumb stuff using made up impossible numbers](https://www.lesswrong.com/posts/GrtbTAPfkJa4D6jjH/confidence-levels-inside-and-outside-an-argument) and on the other hand, we dismiss those numbers and fall back on there’s-a-chancism. These two phenomena don’t always perfectly compensate one another (as examples show in both posts), but common sense is more reliable that it may seem at first. (I’m not saying it’s the correct approach nonetheless.)
