An automated climate control system for an agricultural facility triggers an emergency ventilation sequence, denoted by the output state VVV. The logic governing this system is given by the Boolean expression:
V=(P AND NOT Q) OR (R AND S AND NOT T)V = (P \text{ AND NOT } Q) \text{ OR } (R \text{ AND } S \text{ AND NOT } T)V=(P AND NOT Q) OR (R AND S AND NOT T)
where PPP, QQQ, RRR, SSS, and T T\,T are independent binary sensor inputs representing physical environmental parameters.
State how many rows (excluding any headings) would be required in a complete truth table to represent all possible states of this system.
