Truth Tables for the Conditional and Biconditional · Example 4

Construct a truth table to analyze all possible outcomes for each of the following statements, then determine whether they are valid.

(a) $p \land q \leftrightarrow p \land \sim q$
(b) $p \lor q \leftrightarrow\sim p \lor q$
(c) $p \to q \leftrightarrow\sim q \to\sim p$
(d) $p \land q \to\sim r \leftrightarrow p \land q \land r$
