Abstract
Since the world is full of indeterminacy, the neutrosophics found their place into contemporary
research. In neutrosophic set, indeterminacy is quantified explicitly and truth-membership,
indeterminacy-membership and falsity-membership are independent. So it is natural to adopt for
that purpose the value from the selected set with highest degree of truth-membership,
indeterminacy membership and least degree of falsity-membership on the decision set. These
factors indicate that a decision making process takes place in neutrosophic environment. In this
paper, we introduce and study the probability of neutrosophic crisp sets. After given the
fundamental definitions and operations, we obtain several properties and discussed the relationship
between them. These notions can help researchers and make great use of it in the future in making
algorithms to solving problems and manage between these notions to produce a new application
or new algorithm of solving decision support problems. Possible applications to mathematical
computer sciences are touched upon.
