Diagramming Practice – Final Exam

Diagram the following conditional statement and find its contrapositive: “You cannot pass this class unless you get a 115 on the final exam.”

Answer

To diagram a statement involving the word “unless,” you should first change the word “unless” to the phrase “if not.”  Then, you can diagram the changed sentence the same way that you would diagram an “if” statement.  So, the sufficient condition is “NOT get a 115 on the final,” and the necessary condition is “NOT pass.”
