The output of the following combinational circuit is F.
q10 (1)
The value of F is :
(A) P1+P2P3
(B) P1+P2P3
(C) P1+P2P3
(D) P1+P2P3


Answer: (B)

Explanation: We know that (A+B)(A+C) = A + BC
ON the basis of Given question OR gates will produce output:
(P1+P’2+P’3)
(P1+P’2+P3)
(P1+P2+P3)

AND gate will take all three input produced by OR gate and generate (P1 + P’2P’3) as output.

So, option (B) is correct.
