We extend the Fortuin–Kasteleyn–Ginibre (FKG) inequality to cover multiple events with equal pairwise intersections. We then apply this inequality to resolve Kahn's question on positive associated measures, as well as prove new inequalities concerning random graphs and probabilities of connection in Bernoulli percolation.
