| Abstract: | In this research, quotient strategies and their influence on decision-making in situations that involve the comparison of probabilities are analyzed. In order to achieve this, classical probability situations modeled with urns were designed. In each situation, two urns with simple extraction, involving or not proportional relationships, were proposed to third grade secondary school students. The analysis was carried out through the categorization of the results based on the relationships established between the components of the urns (favorable, unfavorable and possible cases). The study concluded that when comparing probabilities, students not only resort to the quotient (ratio): favorable case numbers among the number of possible cases to make their choice, but to others where they also include unfavorable cases.
