To start, here’s a revision of how to determine an argument’s validity and whether it is cogent or sound.Is it possible that both all of the premises are true and the conclusion is false?If yes — then it is invalid and unsound / not cogent.If no — then it is definitely valid. But are the premises actually true? If yes, then it is sound/cogent. If not, it is unsound / not cogent.

Are the following valid (V) or invalid (I) and then sound (S) or unsound (U)?

Monica is a brunette and is short, therefore she is a short brunette.

Chandler is blonde and all the blondes I know are from Finland, therefore Chandler is from Finland.
