with questions that have "And in the trigger"- I'm a bit confused about the validity of the contrapositives.
If both P and Q are selected, then R is selected.
P and Q-> R
The contrapositive being-
-R-> -P or –Q
However, since it’s P AND Q that are sufficient to cause R
Couldn’t you not have R (-R) and still have P? But not Q. Alternatively, have Q, but not P.
Any explanation would be saaahhweeetttt.

So you can have ~P and have Q or the other way around; and you can also not have both of them.
to give an example:
if you drink and you drive -> you can get a DWI.
if you can't get a DWI -> you are either not drinking, not driving or not doing either one.
