What is Law of Compound Probability

Classical probability is historically presented as the first interpretation of random phenomena. Even with its application limits, it represents the starting point for the main concepts of probability calculation. In class it is the most represented formulation, and, in some cases, it is presented as a standard definition of probability. In the chapter, after presenting the classic objects (coins, marbles, dice, playing cards) normally used to introduce the theme, the panorama is widened thanks to the introduction of less common artifacts and the use of examples that can provide useful insights for further study. The path starts from the concepts of trial and event and ends with the Bayes theorem.
