The expected utility is the sum of utilities weighted by probability. The probabilities sum to 1, and since the utilities are all 1, the weighted sum is also 1. Therefore every action scores 1. See Expected utility hypothesis.

Thanks. (Edit: My intended meaning doesn't make sense, since # of possible outcomes doesn't change, only their probabilities do. Still a useful heuristic, but tying it to utility is incorrect).
