Artificial Intelligence - Fuzzy Logic MCQ (Multiple Choice Questions)

Here are 25 multiple-choice questions (MCQs) related to Artificial Intelligence, focusing specifically on Fuzzy Logic. Each question includes four options, the correct answer, and a brief explanation. 

These MCQ questions cover the fundamental concepts and applications of Fuzzy Logic in Artificial Intelligence, highlighting its role in dealing with imprecision, vagueness, and uncertainty in various domains.

Answer:

c) Problems involving vague or ambiguous information

Explanation:

Fuzzy Logic is used in AI to handle problems involving vague, ambiguous, or imprecise information, allowing for reasoning in situations where traditional binary logic is inadequate.

2. The fundamental concept behind Fuzzy Logic is that truth values:

c) Are always undefined

d) Depend on network conditions

Answer:

b) Can be any real number between 0 and 1
