In this last chapter of the probability part, the laws of probability are presented. These
laws are very important even in statistics. They govern difficult phenomena by simple
mathematical formulas, obtained after a few developments. The mastery of these laws will
allow the classification of the phenomena by the amounts of the probabilities and the number
of elements in the samples (or the population).
Keywords: Binomial Law, Central limit theorem, Distribution function, Normal law, Poisson's Law, Uniform law.
