Elements of probability calculation

Combinatorial calculus: counting principle, simple permutations and theorem, permutations with repetition and theorem, simple combinations and theorem, binomial coefficient, simple dispositions and theorem, dispositions with repetitions and theorem.

The case: historical references; Events and their algebra: standard event, implication between events, equal events, opposite event, logical sum, logical product, property of events, incompatible events, logically independent events, sample space, conditioned events.

The different definitions of probability: classical, frequentistic, axiomatic, subjective, elementary propositions on the probability of events. Probability assessments in the hypothesis of equally probable elementary cases: card games, birthday problem.

Notes on conditional probability: compound probability theorem, stochastically independent events, Bayes formula, Bayes theorem, a priori probability, posterior probability. Applications
