Haha.
It's really not as complicated as it looks. One scale is: "how
likely is this bad thing to happen?" And the other scale is, "how much will it
hurt us if it does happen?"
And you just multiply those two by each other to get a score. The lower the score, the safer you are going for it in spite of the risk.
Here, I'll give examples from a few of the extreme corners:
Ex 1: You are considering sleeping with the flirty wife of a Navy Seal. The likelihood he is going to eventually catch you is very high. And the likelihood he will rip your arms off if he does catch you, also very high. So like .9 times .9. That's an 81% chance you really can't afford to do this thing. So don't do it.
Ex 2: You are considering slapping your little brother up side the head. Your parents are not home. And in any case, they don't like your little brother, either. The likelihood they'll catch you is very low. And the likelihood they'll do anything harsh to you if they do find out, also very low. So along the lines of .1 times .1. That's a 1% chance this will really cost you anything. So go ahead, slap away.
Ex 3: Someone left the keys running in a Brinks delivery truck. There is absolutely no one in view. You can easily slip inside, grab a bag of money, and walk away. You're almost positive no one will ever know it was you, the likelihood you'll get caught is super low. On the other hand, if you do get caught, you'll end up being nicknamed Sally on Cell Block C of the federal prison in Kansas. So it's a .1 times .9 kind of situation, which comes out somewhere around 45% or so. That's a tough one. Do you feel lucky?
See? Not hard to do, once you have a feel for it.
Go Vols!
