This paper describes the use of the equiprobability bias, which has been identified in the reasoning of 908 prospective secondary school teachers of Mathematics and Biology, in the province of Mendoza, Argentina. We analyse the arguments justifying the responses given to twelve research questions in which students are asked to justify the assignment of a certain degree of probability for a given phenomenon and the events that arise. The situations were selected taking into account the content of the item and the
degree of probability so that the items used are representative of the context of games, daily life and physical-natural context.
