Truth tables are used to determine the validity or truth of a compound statement*. Another way to say this is: For each assignment of truth values to the simple statementswhich make up X and Y, the statements X and Y have identical truth values. 2-19-2020 Truth Tables, Tautologies, and Logical Equivalences Mathematicians normally use a two-valued logic: Every statement 2 0 obj The truth table is completed … Next, we display the truth tables of p^qand p_q: p q p ^q T T T T F F F T F F F F p q p _q T T T T F T F T T F F F Let pand qbe two propositions. • A compound statement is composed of one or more simple statements.
