The definition given differs from Webster.
Webster says 2 : the occurrence of events that happen at the same time by accident but seem to have some connection; also : any of these occurrences (Merriam-Webster Online)
Why remove the time element for #2 and why vary the definition based on whether it applies to objects versus events? Allowing for time lag in causation sequencing? Use of language in #1 is unusual. Events occur. Do objects occur? Only if they are considered events--in which case, the distinction on which the second definition is based seems wanting.

Could it also have the alternative spelling form co-incidence, similarly to co-author, co-operation, co-induction etc? I suppose that lack of such form can be explained by historical reasons: the word was apparently borrowed from French as coïncidence with gradual omission of the diaeresis, not by adding of the prefix co- to already existing incidence. --95.165.214.123 06:50, 25 July 2013 (UTC)
