The article studies the knowledge of students, prospective primary school teachers, about relationships between disjoint and complementary events from the three objectives: 1) To study the performance of students in recognizing the truth/falsehood of the enunciated relations between disjoint and complementary events; 2) To characterize the justifications presented by the students to affirm the truth/falsehood of the enunciated relations and 3) To draw consequences for the training in Probability of prospective primary school teachers years. Participated in the study 37 students of the 2nd year of the Degree in Basic Education, who attended a university in the north of Portugal. Study data are the responses given by students to a task involving relationships between disjoint and complementary events. In terms of results, there was a reasonable performance of the students in terms of the truth/falsehood of the relationships, which worsened a lot in terms of justifications.
