Probability is generally concerned with dealing with problems of a random or uncertain nature. The fact that it arises and develops from the analysis of gambling is something that cannot be overlooked. From the point of view of teaching, in addition to historical aspects, it is important to point out the importance of putting students in front of situations that, if not known, can lead to incorrect behavior and pathological attitudes. For this reason, the authors tried to emphasize not only the theoretical aspects, but above all the certainty that you always play “against the dealer” with an expected loss assessable for the various games.
