Experimental intermediate-mass-fragment multiplicity distributions for the [ital E]/[ital A]=80 and 110 MeV [sup 36]Ar+[sup 197]Au reactions are shown to be binomial at all excitation energies. From these distributions, a single binary event probability [ital p] can be extracted that has a thermal dependence. Thus, it is inferred that multifragmentation is reducible to a combination of nearly independent emission processes. If sequential decay is assumed, the increase of [ital p] with excitation energy implies a contraction of the time scale that is qualitatively consistent with recent fragment-fragment correlation data.
