Law of Disjunctive Inference

Показать описание
We introduce another law of inference we can use in our logic proofs called the Law of Disjunctive inference. When a disjunction is true, and one of its disjuncts is not true (false), then the other disjunction is true.

thanks ms. basias! i think one small think i noticed was that in number 10, step 7 of the proof the reason (law of disjunctive inference) would be from steps 5, 6 (not 6, 7). this video was really easy to follow helped apply each of the laws.
