A premise is a statement in an argument that provides reason or support for the conclusion. There can be one or many premises in a single argument.Important PointsStatement I: An argument form that allows for a substitution instance having true premises and a false conclusion is an invalid form.A conclusion is a statement in an argument that indicates what the arguer is trying to convince the reader/listener.The argument really does have all true premises and a true conclusion, but still, it is invalid”because it is possible for an argument with this structure to have true premises and a false conclusion. eg: P1: All dogs are mammals. P2: All cats are mammals. C: All cats are dogs. True premises can lead to either a true or a false conclusion in an invalid argument.Thus the statement I is correct. Statement II: Every argument with true premises and a false conclusion is INVALID.A valid argument cannot possibly have all true premises and a false conclusion. If some argument really does have all true premises and a false conclusion, then it is obviously possible for such an argument to have true premises and a false conclusion. So the argument is invalid.Thus statement II is correct.Hence we can conclude that both Statement I and Statement II are true.
