If you use RandomForest without wrapping it into MultiClassClassifier (or some other binary decomposition method such as END), you will get a multi-class random forest that estimates multi-class probabilities directly. In recent versions of WEKA, there is actually an option in RandomForest that enables you to output the trees of the learned forest. You can inspect the trees to verify this.
