Given a probability space, to derive a probabilistic representation for exact functionals, we endow them with two probabilistic conditions: law invariance and the Fatou property. The representation theorem for exact functionals lays a probabilistic foundation for nonatomic scalar measure games. Based on the notion of $P$-convexity, we also investigate the equivalent conditions for the representation of anonymous convex games. \itemrv{~} \itemcc{} \itemut{} \itemli{doi:10.1007/978-3-642-31724-8\_24} \end
