\b[No.] In a <simple cooperative game>, a player's <marginal contribution> along any <permutation> is zero or one. With three players there are six equally likely <permutations>, so every <Shapley value> is an integer multiple of $1/6$, by the <Shapley value denominator in a simple game>. But $6(5/12)=5/2$ and $6(3/12)=3/2$ are not integers. The vector sums to one, but fails this necessary denominator condition.
