In which of the following instances, deductive argument is invalid ?
When its premises are true but conclusion is false.
A deductive argument is valid when its conclusion follows necessarily from its premises, so that the premises cannot all be true while the conclusion is false.
Validity depends on the form of the argument, not on the actual truth of its statements. False premises with a false conclusion, true premises with a true conclusion, and false premises with a true conclusion can all occur in valid arguments.
The one combination a valid deductive argument can never have is true premises leading to a false conclusion. Whenever this happens, the form itself has failed and the argument is invalid.
Hence, When its premises are true but conclusion is false.
