Best answer 4 votes 4 votes Answer is option a. AB + ~AC = 1................(1) AC +B = 0....................(2) Now substitute A=0,B=0,C=1 in equation(1) & (2) From equation (1) 0.0+1.1=1 1=1 LHS=RHS hence true. From equation (2) 0.1+0=0 0=0 LHS=RHS hence true. nandini gupta answered Jan 17, 2017 • selected Jan 17, 2017 by Bikram nandini gupta comment Share Follow See all 2 Comments See all 2 2 Comments reply vinay25 commented Jan 25, 2017 reply Follow Share 1,0,0 also gives same result? 0 votes 0 votes nandini gupta commented Jan 25, 2017 reply Follow Share 1,0,0 will not satisfy the equation AB + ~AC = 1 On LHS =1*0+0*0 =0 But RHS is 1 Hence LHS is not equal to RHS 2 votes 2 votes Please log in or register to add a comment.
