Conditional probabilities with a quantal and a kolmogorovian limit
- 35 Downloads
We give a definition for the conditional probability that is applicable to quantum situations as well as classical ones. We show that the application of this definition to a two-dimensional probabilistic model, known as the epsilon model, allows one to evolve continuously from the quantum mechanical probabilities to the classical ones. Between the classical and the quantum mechanical, we identify a region that is neither classical nor quantum mechanical, thus emphasizing the need for a probabilistic theory that allows for a broader spectrum of probabilities.
