Can we say that the classical (Kolgomorov axiomatization) and quantum probabilities results are different, when we consider only the statistical results (i.e. the probability of events)? Can we really distinguish a classical statistical result from a quantum one (i.e. the born rules)? What are the real differences between these 2 mathematical tools when we consider only the experimental results (the statistics or if you prefer the frequencies of the events)? Seratend.
