  The notion of conditional entropy is extended to noncomposite systems. The
q-deformed entropic inequalities, which usually are associated with
correlations of the subsystem degrees of freedom in bipartite systems, are
found for the noncomposite systems. New entropic inequalities for quantum
tomograms of qudit states including the single qudit states are obtained. The
Araki{Lieb inequality is found for systems without subsystems.
