It is shown, that, generally, the magnitude of the fluctuations is proportional to $N^{3/4}$, where $N$ is the number of produced events, which should be compared with $N^{1/2}$ for the case of independent events. The formula eligible for the use in an analysis of experimental data is provided.6 pages, LATEXHigh Energy Physics - Phenomenologytext
