Consider the expression X = A BC + B CA + C AB . Find the value of X if A = B = C = 1 .
Options
- A0
- B1
- C-1
- D2
Correct answer
A. 0
Step-by-step solution
Given the Boolean expression X = A BC + A B C + AB C . Substituting the values A = 1 , B = 1 , and C = 1 , we get the complements as A = 0 , B = 0 , and C = 0 . Substituting these into the expression: X = (0)(1)(1) + (1)(0)(1) + (1)(1)(0) X = 0 + 0 + 0 = 0 Thus, the value of X is 0 .
