Logical/semantical inverse of the definition of synchronicity?

'Definition' of synchronicity:

"The occurrence of highly improbable coincidences between events where there is no causal link."

What would be the logical/semantical inverse?

- The nonoccurrence of highly probable coincidences between events where there is a causal link.

- The occurrence of highly probable coincidences between events where there is no causal link.

- The occurrence of highly improbable concurrence between events where there is no causal link.

Or another one?
