Abstract : We propose a macroscopical classical physical entity, giving a detailed description of
the preparation apparatuses and the preparations (states) of this entity. We consider experiments
that can be performed on the entity, and give a detailed description of the measurement
apparatuses, and the measurements used in these experiments. We investigate the collection of
probabilities for the outcomes of the measurements the entity being prepared in a given state.
Therefore we use the ordinary meaning of probability as approximate relative frequency of
repeated experiments, hence experiments consisting of equivalent measurements on equivalently
prepared entities. We show that the collection of probabilities that results in this way for our
macroscopical entity is the same as the collection of probabilities for the outcomes of the Stern-
