  New in the probability theory and eventology theory, the concept of Kopula
(eventological copula) is introduced. The theorem on the characterization of
the sets of events by Kopula is proved, which serves as the eventological
pre-image of the well-known Sclar's theorem on copulas (1959). The Kopulas of
doublets and triplets of events are given, as well as of some N-sets of events.
