Use a truth table to determine whether each statement is a tautology, a self- contradiction, or neither. \((p \wedge q) \wedge(\sim p \vee \sim q)\)
a. Use a truth table to show that \(p \rightarrow q\) and \(\sim p \vee q\) are equivalent. b. Use the result from part (a) to write a statement that is equivalent to If a number is even, then it is divisible by \(2 .\)
Under what circumstances should Euler diagrams rather than truth tables be used to determine whether or not an argument is valid?
From Alice in Wonderland: "Alice noticed, with some surprise, that the pebbles were all turning into little cakes as they lay on the floor, and a bright idea came into her head. 'If I eat one of these cakes,' she thought, 'it's sure to make some change in my size; and as it can't possibly make me larger, it must make me smaller, I suppose." " Alice's argument: If I eat the cake, it will make me larger or smaller. It can't make me larger. \(\therefore\) If I eat the cake, it will make me smaller. Translate this argument into symbolic form and determine whether it is valid or invalid.
If a symbolic statement does not contain parentheses, how are the grouping symbols determined?
