On Fuzzy Probabilities in Bayesian Games

This work proposes an application of fuzzy probabilities, respecting an arithmetic restriction, in order to estimate unknown types of players in a bayesian game, thus configuring a fuzzy bayesian game. To this end, besides defining the operations needed for this application, a hypothetical example of a bayesian game is presented and then this exemplified situation is used to analyze the behaviour of the game with fuzzy probabilities.
