### In/Out rule question

I just want to make sure I am understanding this right...

let's say the rule says If Z, then not U

so this would mean z<--/-->u ( that if one is in then the other is out or both can be out?)

And then

If a rule said If not Z, then U this could mean that one is in or both are you in?

Do I have this correct?

Correct.

Given this rule you can have just Z, just U, or both, but you can never have neither present. I believe that is what you said but I'm clarifying just in case.
