ABSTRACT
With little doubt, the theory of probability considered in the previous chap-
ters is an elegant and consistent mathematical construction worthy of study
in its own right. However, since it all started out from the need to obtain
answers and/or make predictions on a number of practical problems, it is
reasonable to expect that the abstract objects and propositions of the theory
must either have their counterparts in the physical world or express relations
between real-world entities.
