Proceedings of Business and Social Sciences Research Conference 10 - 11 December 2015, Ambassador Hotel, Bangkok, Thailand, ISBN: 978-1-922069-90-0 Truncated Probabilities, Generalized Fermi-Dirac Entropy, Truncated Statistical Distributions, and Some Applications C. R. Bector, S. S. Appadoo and G. S. Sohi A generalized format of Fermi-Dirac entropy with truncated probabilities is introduced. A formula for obtaining truncated probabilities is derived and their applications in some well known statistical distributions are suggested. Furthermore, a simple application of the truncated probabilities in an investment problem is also suggested. Towards the end, an extension of the results, obtained in this paper, is suggested under fuzzy environment. It is expected that the results derived in this paper will also find applications in a variety of other areas in management. Main References [1]. Kapur, J.
