. Given a proof by contradiction (PBC) whose support is 1 and whose original premises are false, the negation of the conclusion (i.) is true (ii.) might be true (iii.) is false (iv.) can't be evaluated for truth. (Ch 15)
Homework Answers
Option 3 is the correct answer.
Is false - whose original premises are false the negation of the conclusion is false.
