- (a) Define $\alpha$-cut and strong $\alpha$-cut for a fuzzy set. Given fuzzy set $A=\{1 / x 1+0.8 / x 2+0.3 / x 3+0.2 / x 4\}$. Find $A \alpha=0.3$.
- (b) What is law of excluded middle and law of contradiction? With an example verify whether the law is satisfied for a fuzzy set.
- (a) Two discrete fuzzy sets are given by $A=\{1 / 2+0.5 / 3+0.3 / 4+0.2 / 5\}$ and $B=\{0.5 / 2+0.7 / 3=0.2 / 0.4=0.4 / 5\}$ Find complement, union, and intersection of the sets. Apply De Morgan's principle to the sets.
- (b) Two discrete fuzzy sets are given by $A=\{0.1 / 0+0.2 / 1+0.4 / 2+0.6 / 3+1 / 4\}$ and $B=\{1 / 0+0.7 / 1+0.2 / 2+0.4 / 3+0 / 4\}$ Find $A \cup B, A \cap B, A \cup \bar{A}, B \cup \bar{A}$ Module - II
