Do this: . Apply Truth Table to proof the following Laws: 1. Equivalences (-) =P (P v Q) = (PQ) 2. The contra positive law ( PQ) = (-Q-P) 3. De Morgan's law - (P VQ) = (-PA-Q) and (PAQ) = (-PV-Q) 4. The commutative laws (PAQ) = (QAP) and (P VQ) = (QVP) 5. Associative law (( PQ) AR) = (PA (QAR)), (( PQ) VR) = (Pv (QR)) Distributive law PV(QAR) = (PVQ) (PVR), PAQVR) = (PAQ) (PAR)
