Dear Mohammed Alkailany,

The stochastic process is a non-deterministic process is governed by random variables, while the fuzzy set whose variables are uncertain and are defined in an interval between [0 - 1].

However fuzzy and stochastic is being used inter-changeably for uncertainty. we can say that there is a common sense to the process.

I am agree with well detailed answers of Mohamed-Mourad Lafifi, Nabil Shaukat and Zoleikha Soori.
