subjective

We have seen in The logical view: probability as objective degree of belief that "logical" probability, defined as a degree of belief which it is rational and objective to hold given the available evidence, can give rise to some contradictory results. However, in the 1920s Frank Ramsey in Cambridge [1] and Bruno de Finetti in Italy [2] independently proposed a radically different interpretation of probability which avoids these paradoxes by asserting that probability is a subjective degree of belief.
