There are two concepts of probability and statistics, Bayesianism and 
frequentism (orthodox view), which formulate probability in somewhat 
different ways. I would say that quantum mechanics might be the most 
rigorous definition of probability. I would be tempted to say it is more 
Bayesian than frequentist.
