  The theory for manifestation of stochastic appearance of embryos in the
global decay of metastable phase has been constructed. The regime of droplets
growth is supposed to be both free molecular one and diffusion one. The
deviation for a mean droplets number from the value predicted by the theory
based on averaged characteristics have been calculated. The value of dispersion
for the distribution of the total droplets number in particular attempt has
been also calculated analytically. Comparison with results of numerical
simulation has been given and the correspondence between simulation and
analytical approximate results is rather good.
