A method is proposed for measuring the uncertainties due to lack of information while choosing the strategies in fuzzy game theory problems. The fuzzy payoff table of this problem gives an insight into the derivation of the appropriate fuzzy probabilities for the players strategies. This derivation is based on the concept of probabilities from fuzzy payoffs or fuzzy observations. Different probability combinations of the strategies from the different fuzzy sets of fuzzy probabilities are taken and are used to measure the uncertainties inherent in the problem.
