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 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.
