Probability statistics is a subject in many universities, because of its applicability. For medicine, probability statistics, first of all probability plays an important role, in addition to providing logical thinking and rigorous reasoning in the diagnosis and treatment of diseases, it also equips knowledge in the beginning of medicine. At the University of Medicine and Pharmacy, Thai Nguyen University, we have taught the probability part for students of Medicine doctors for the same purpose. Therefore, the probability problems given in our probability lesson need to be associated with medical knowledge or medical situations. In this paper, the author introduces such problems, and also outlines some common classical probability problems for comparison through each part of probability teaching. Through each problem, the author analyzes the goal or knowledge that we want to equip medical students there.
