We propose a probabilistic three-party communication complexity scenario: with a prior entangled tripartite pure state, to learn the value of a particular function determined by each communication player. It results in less communication than is required with only classical random correlations. If they share a Greenberger-Horne-Zeilinger (GHZ) state, this protocol is deterministic.
