The reduced expression of the Boolean function is:
The reduced expression of the Boolean function $F(P, Q) = P' + PQ$ is:
- (a)$P' + Q$
- (b)$P$
- (c)$P'$
- (d)$P + Q$
Answer
Answer
AICorrect option: (a)
Answer: (a) $P' + Q$
$P' + PQ = (P' + P)(P' + Q) = 1 \cdot (P' + Q) = P' + Q$ (distributive law, then complement law).
