Probability, Expectation Value and Uncertainty
more or less directly from the classical theory of probability and statistics. Roughly speaking, it represents the (probability-weighted) average value of the results of many repetitions of the mea-surement of an observable, with each measurement carried out on one of very many identically prepared copies of the same system.

This linking of particular states with particular measured results provides a way that the observable properties of a quantum system can be described in quantum mechanics, that is in terms of Hermitean operators.

Chapter 3: The basic concepts of probability
www.ams.sunysb.eduThe classical definition of probability If there are m outcomes in a sample space, and all are equally likely of being the result of an experimental measurement, then the probability of observing an event that contains s outcomes is given by e.g. Probability of drawing an ace from a deck of 52 cards. sample space consists of 52 outcomes.
7.1 Sample space, events, probability
www3.govst.edu• Probability of an event E = p(E) = (number of favorable outcomes of E)/(number of total outcomes in the sample space) This approach is also called theoretical probability. The example of finding the probability of a sum of seven when two dice are tossed is an example of the classical approach.
