What are the truth values of a proposition?
A proposition has only two possible values: it is either true or false. We often abbreviate these values as T and F, respectively. Given a proposition p, we form another proposition by changing its truth value….2.1: Propositions.

|---|---|
| T | F |
| F | T |
