Every case, one row each

A truth table lists every combination of truth values for the statements involved. With $n$ statements there are $2^n$ rows.

$P \land Q$ (“and”) is true only when both are true. $P \lor Q$ (“or”) is true when at least one is true. $\lnot P$ (“not”) flips the truth value.

$P \Rightarrow Q$ is false only when $P$ is true and $Q$ is false.
