A General phenomenon could be divided into two types, that one is the determinacy phenomenon and the other is the indeterminacy phenomenon. The determinacy phenomenon could be handled by crisp set theory of binary logics, while the indeterminacy phenomenon could be further divided into a random phenomenon and a fuzzy phenomenon. In reality, using binary logics as the basis of reasoning does not fit the actual situation and thus different perspectives should be used to treat problems. Fuzzy perspectives and the concept of random variables could be used to discuss related problems. This paper uses basic algorithm of fuzzy set to deduce the related features of multivariate fuzzy random variables, and presents examples for demonstration. A method that is different from Yao's is used to infer related features.
