By using propositional variables, logical connectives, and quantifiers, determine whether the argument is valid. If it is valid, what rule of inference is being used? If it is not, what logical error occurs? The argument: If the orchestra could not play classical music or the refreshments were not delivered on time, then the birthday party would have been canceled and Amelia would have been angry. If the party were canceled, then refunds would have had to be made. No refunds were made. Therefore the orchestra could play classical music.
