Probabilidade: uma releitura do livro O andar do Bêbado

Abstract

The present work aims to provide the teacher of Basic Education with support for the planning of his classes, presenting a theory summary and interesting problems that counterintuitive, as the Monty Hall s problem, and others less known as birthdays problem (conditional probability), truel s problem (probability of union of infinite events), Canadian lottery s problem (about Stirling numbers). This text was based on the book The Drunkard's Walk, the best seller of world-renowned science popularizer Leonard Mlodinow. Many of the problems solved here were taken from that text, and those added from other sources followed the same idea. Some problems deal with practical situations in daily life, such as the interpretation of the probabilities of medical examinations, revealing errors made by health professionals themselves. Finally, we present software that implements a game that simulates the Monty Hall s problem, with source code included in the appendix.
