The article reveals the importance of interdisciplinary connections as an important component of interdisciplinary integration in order to optimize the educational process. An attempt is made to develop and practically test the technology of forming stochastic representations, effective methods, forms and means of teaching stochastic elements of students of non-mathematical specialties in the process of teaching physical and mathematical disciplines. The article presents examples of stochastic problems for students of biologists, physicists, chemists, and economists. Stochastic tasks are quite capable of solving and contributing to the development of logical thinking and professionally meaningful knowledge and skills of students; increase the activity of educational activities, contribute to the creation of a positive motivation for the study of physics or mathematics; increase the effectiveness of learning. The purpose of the article is to develop and practically test the technology of forming stochastic representations, effective methods, forms and means of teaching stochastic elements using interdisciplinary connections. To achieve the goal, we used theoretical (systematic and comparative analysis of literature, work programs, pedagogical process on the problem of research, generalization and systematization of scientific and theoretical positions in order to obtain a coherent picture of the current state of research and the possibilities of improving the approaches of students to stochastic problems) and empirical research methods (diagnostic and observational to assess students' perceptions of material). We conclud that tasks of a stochastic nature contribute to the formation of students' logical thinking, increase the activity of educational activities, and contribute to improving the efficiency of student learning.
