The paper deals with a new approach to probability distributions identification, which is based on skewness and kurtosis of some well-known distributions. These distribution’s skewness, and kurtosis determine curves, or points on the coordinate plane “skewness – kurtosis”. The sample skewness, and kurtosis alt-hough determine a point on this plane. If this point belongs to the curve or the set of points, or places near them, we need to verify the hypothesis that the sample belongs to the corresponding distribution. The ap-proach proposed is adapted to educational use in probability theory and statistics.

The author proposes the method of teaching students dealing with the economy with the part of the proba-bility theory concerning the discrete and continuous distributions. Particular model of the stream of tele-phone calls lead to the discrete and continuous distributions. With the example of Poisson and exponential distribution we can see how one can use the comparison of different types of distribution to achieve the best understanding and remember their features.

The article is devoted to the questions of mathematics teaching to the students that are specialized in economy fields. The author proposes to introduce the new mathematical conceptions by giving an economical model example. The offered method allows students not only to become proficient in mathematics but also to learn the practical benefit of abstract mathematical conceptions studying. The students gain in addition some experience in creation, analysis and application of the economical phenomena models.
