  Corresponding to AAA-2 (abduction) we have the following argument: X% of Ms are Ps (Rule); X% of Ss are Ps (Result); therefore, all Ss are Ms (Case). Construing this argument as applying to drawing balls from urns, the argument becomes: X% of the balls in this urn are red; X% of the balls in this random sample are red; therefore, all the balls in this random sample are taken from this urn. Again here we have the character of an educated guess or inference to a plausible explanation.
