He is famous for the aphorism: “Probability does not exist.” By this he meant that probability reflects an individual’s beliefs about reality, rather than a property of reality itself. WebA conditional probability P(A B) in de Finetti's system is interpreted as a conditional bet on A, available only if B is determined to have happened. De Finetti was able to show that the probabilities corresponding to a coherent set of bettings odds must satisfy the …
