The present work studies the importance of Bayesian reasoning in the everyday life providing a series of characteristic applications of the Bayes’ rule and the conditional probabilities. It is shown that the Bayes rule could be considered as an interface between the traditional bivalent logic and the Zadeh’s infinite-valued fuzzy logic. The importance of the Bayesian reasoning for the whole science is also theoretically justified.
