An automated climate control system in a vertical farm regulates ventilation (output YYY) using three binary sensor inputs:
The system activates the output ventilation sub-unit according to the Boolean logic expression:
Y=(P AND NOT Q) OR (NOT P AND R)Y = (P \text{ AND } \text{NOT } Q) \text{ OR } (\text{NOT } P \text{ AND } R)Y=(P AND NOT Q) OR (NOT P AND R)
Complete the truth table for the output YYY.
