  The theory of probability and the quantum theory, the one mathematical and
the other physical, are related in that each admits a number of very different
interpretations. It has been proposed that the conceptual problems of the
quantum theory could be, if not resolved, at least mitigated by a proper
interpretation of probability. We rather show, through a historical and
analytical overview of probability and quantum theory, that if some
interpretations of the one and the other go along particularly well, none
follows in a unique way.
