How does the truth table for (P∧Q)∨R(P \land Q) \lor R(P∧Q)∨R differ from (P∨R)∧(Q∨R)(P \lor R) \land (Q \lor R)(P∨R)∧(Q∨R)?
They have the same truth values for all inputs.
The first is a tautology, the second is a contradiction.
They differ when RRR is True.
They differ when PPP and QQQ are both False.
