Select the code which is not correct in the context of deductive argument with two premises : Correct Answer An argument with two true premises and a false conclusion may be valid.

An argument

  • It is a set of statements that consists of a conclusion and the statements said by the arguer to lead to that conclusion.
  • Deductive reasoning is a logical assumption or conclusion, that is drawn from valid or invalid premises. In deductive reasoning, no other facts, other than the given premises, are considered.
  • Deductive reasoning goes from a general to a specific instance.
  • It based on a premise and then follows accordingly. 
  • Thus, deductive reasoning is the method by which, conclusions are drawn on the basis of proofs, and not merely by assuming or thinking about a predetermined clause.

Deductive arguments

  • It can only be valid or invalid, sound or unsound or true or false, because the statement that is derived may be true, but in the context of the derived conclusion, it may not be valid.
  • A deductive argument can be valid, only if the conclusion necessarily follows from the premises given. If the conclusion is incorrect, then one of the premises must be faulty or true only for a specific situation, which is not applicable to all situations.
  • A valid deductive argument with true premises is said to be sound, whereas, a deductive argument that is invalid or has one or more false premises or both, is said to be unsound.
  • An argument is valid when both the premises are true and the conclusion that is derived from them cannot be false.

Hence, the only situation that is not correct in the context of a deductive argument with two premises is- An argument with two true premises and a false conclusion may be valid.
