So this might be a too simplistic question on many accounts.(adsbygoogle = window.adsbygoogle || []).push({});

My pchem professor said to us that in QM, anything that can happen will. And it's a matter of probability, right?

I guess I'm just curious what the scales are for something like, say, walking through a wall (the go-to example for a lot of popular science books on QM)? Like, 1 in a billion or what?
