Argument from fallacy is the formal fallacy of analyzing anargument and inferring that, since it contains a fallacy, its conclusion must be false. It is also called argument to logic (argumentum ad logicam), fallacy fallacy, fallacist's fallacy, and bad reasons fallacy.
Fallacious arguments can arrive at true conclusions, so this is an informal fallacy of relevance.
Bill: You have just fallaciously affirmed the consequent. You are incorrect. Therefore, Ginger is not a cat.
Tom: I speak English. Therefore, I am English.
Bill: Americans and Canadians, among others, speak English too. By assuming that speaking English and being English always go together, you have just committed the package-deal fallacy. You are incorrect. Therefore, you are not English.
Both of Bill's rebuttals are arguments from fallacy. Ginger may or may not be a cat, and Tom may or may not be English. The fact that Tom's argument was fallacious is not, in itself, sufficient proof that his conclusion is false.
Joe: Bill's assumption that Ginger is not a cat uses the argument from fallacy. Therefore, Ginger absolutely must be a cat.
That one can invoke the argument from fallacy against a position does not prove one's own position either, as this would be an argument from fallacy itself, as is the case in Joe's argument.
Appeal to probability – is a statement that takes something for granted because it would probably be the case (or might be the case).
