This exposition provides a proof of the existence of polynomial-size monotone formula for Majority. The exposition follows the main principles of Valiant’s proof (J. Algorithms, 1984), but deviates from it in the actual implementation. Specifically, we show that, with high probability, a full ternary tree of depth \(2.71\log _2n\) computes the majority of n values when each leaf of the tree is assigned at random one of the n values.
