Linking Conditionals Flashcards
De Morgan’s Law
And/or conditionals
Switch sides
Negate
Flip any and’s for or’s
And in the sufficient
Cannot be broken up without changing the meaning
A & B -> C
If you incorrectly write A->
B-> C
Then either item can set of the change when both are needed. It effectively changes it to or based on a mistake in shorthand.
And in the Necessary
A-> B & C
A sets off both B and C without needing anything else. So it can be written as A-> B
->C
Without changing any meaning.
Or in the Sufficient
A or B > C
Either option may give you c so you can split them apart and write it like this
A-> C
B-> C
Or in the Necessary
A-> B or C
A must give you either B or C alone or unless the question directly says it can’t then you can get both.
