In papers [2], [3], [4], [9],[10], [11] the mentioned problem was treated by methods of fuzzy sets theory. Fuzzy sets were considered there as mappings from a set to [0,1] real interval. Here this problem has been considered using fuzzy sets from a more general point of view, as mappings whose co-domain is a special lattice valued monoid. The model developed in this paper is an improvement of the one given in [5]. In the same time it is an anticipatory model since it predicts efficiency of all possible drugs to the disease in question and it suggests the optimal therapy for every patient.

Section 1. Introduction. Probability of fuzzy events according to the idea of L. Zadeh. Section 2. Intuitionistic fuzzy sets of K. Atanassov. Section 3. Intuitionistic fuzzy event (IFE) and its probability according to the results of T. Gerstenkorn and J. Mańko. Section 4. Probability of IFE by using the theorems of decomposition and extension principle of D. Stoyanova. Section 5. Probability of IFE according to the ideas of E. Szmidt and J. Kacprzyk. Section 6. A large example showing utility and helpfulness of using a probability calculus to evaluation of some economic problems. A comparison of different results by using different methods of probability proposals. Section 7. Final remarks.
