Situações cotidianas sob o olhar da probabilidade

Abstract

This research work deals with Probability in daily situations. We performed bibliographic researches with a qualitative approach which the goal was to present the origin, the importance and functionality of the probability theory as seen in daily situations, as for example, in the musical chair dance game, in the cell phone password used to unlock the initial screen and in lottery betting, like the mega-sena. We also describe a brief history of the origin of the probability theory and its most important researchers. We performed probabilistic calculations to the chosen daily situations, from the results it is evident that the theory of probabilities, which has gained great importance over time because of so many applications in various scienti c areas, can be viewed in simple everyday situations.
