74.       If A and B are two fuzzy sets with membership functions
μA(x) = {0.6, 0.5, 0.1, 0.7, 0.8}
μB(x) = {0.9, 0.2, 0.6, 0.8, 0.5}
Then the value of μ(AB)’(x) will be
(A) {0.9, 0.5, 0.6, 0.8, 0.8}
(B) {0.6, 0.2, 0.1, 0.7, 0.5}
(C) {0.1, 0.5, 0.4, 0.2, 0.2}
(D) {0.1, 0.5, 0.4, 0.2, 0.3}
Answer: C
Explanation:
μ(AB)(x) = max{ μA(x), μB(x)}
μ(AB)’(x) = 1- μ(AB)(x)
