A simple game of memory is played where a player is shown two cards for five seconds and then these cards are withdrawn. The player is asked if he has seen one or both of these cards in previous showings. If the user guesses correctly, his score is increased by one for each correct card. If he guesses wrong, then his score is decreased by one for each incorrect card. The pair of cards that are shown are denoted by CardA and CardB. Write the logical relationships involving propositions and propositional operators for the following situations: a) One of the cards was shown before and the user guessed it correctly. b) None of the cards were shown before and the user guessed incorrectly (which may include guessing incorrectly for a single card or for both cards) c) Both cards were shown before and the user guessed incorrectly (which may include guessing incorrectly for a single card or for both cards)
Translate the following arguments in to symbols and determine which rule of inference shows the argument is valid. p: The date is June 25, 2010. q: The temperature is above 80 degrees. r: It is sunny.
