Let # be a binary operator defined as X # Y = X′ + Y′ where X and Y are Boolean variables. Consider the following two statements.
S1: (P # Q) # R = P # (Q # R)
S2: Q # R = R # Q 
Q. 
Which of the following is/are true for the Boolean variables P, Q and R?
  • a)
    Only S1 is True
  • b)
    Only S2 is True
  • c)
    Both S1 and S2 are True
  • d)
    Neither S1 nor S2 are True
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Let # be a binary operator defined as X # Y = X′ + Y′ wher...
S2 is true, as X' + Y' = Y' + X'
S1 is false.
Let P = 1, Q = 1, R = 0, we get different results
(P # Q) # R = (P' + Q')' + R' = (0 + 0)' + 1 = 1 + 1 = 1
P # (Q # R) = P' + (Q' + R')' = 0 + (0 + 1)' = 0 + 0 = 0
