Three approaches to probability free download as word doc. This is to be expected given their equivalence, under some conditions, to the approaches of sections 3 and 4. These approaches, however, share the same basic axioms which provide us with the unified approach to probability known as axiomatic approach. The objectivist approach of probability cannot be applied to all feelings of uncertainty, but only to events liable to occur in identical conditions, during repeated trials.
Since the probability of getting tails is 50% or 0. Thus, judgment is used as the basis for assigning probabilities. Section 3 presents a maximum a posteriori map approach to model selection.
