- Abstract
Probability is an area of mathematics focused on predicting chances, making decisions and analyzing risks, making it one of the main areas of knowledge developed at school. Knowing that the textbook is an essential tool in the teacher's work, this article aims to analyse the perspective of teaching probability in the Probability and Statistics textbooks approved by the PNLD 2021 for High School. Based on documental research, we analyzed the activities considering the meanings of probability, sample spaces and the structuring of events. We found an asymmetry in relation to the meanings, with a great predominance of the classical meaning, the expressive use of discrete sample spaces and limitations in the conceptual approach to important theorems, such as conditional probability for the composition of events. As a result, teachers' skills are fundamental for complementing and correcting the teaching and learning process of probability.
