On Probability Functions based on Assumptions of the Relative Likelihood among Events

الملخص

In probability and statistics much works deals with how to assign probability to a certain events with the study of the manner in which certain specified probabilities change in the light of new information. In this paper we shall discuss the assumptions under which we can represent these information and beliefs in terms of probability distributions, so we shall consider the following question "how does we initially assign to these events the probabilities based on so-called relative likelihoods among events.
