3/3 first time around then 2/3 after blind review... what does that mean

@LauraByrne I thought sufficient was always on the left of the arrow and necessary is on the right. "if a sufficient condition occurs, you automatically know that a necessary condition will also occur."

EG.

If someone gets an A+ on a test, then they must have studied for the test"

"if" being the logical indicator for sufficient and "must" for necessary we can diagram as follows:

A+ -> Study

Contrapositive

/Study-> /A+

If I am pale, then I am sick.

P -> S

If I am not Sick, then I am not pale.

/S -> /P
