We present expansions of real numbers in alternating s-adic series (1 < s ∈ N), in particular, s-adic Ostrogradskii series of the first and second kind. We study the “geometry” of this representation of numbers and solve
metric and probability problems, including the problem of structure and metric-topological and fractal properties of the distribution
of the random variable
