Document Summary
We make the following claim: each card with a vowel on one side has an odd number on the other side. 4 cards on the table are showing 3 , i , 4 and l . Determine which cards you must turn over in order to verify the claim: suppose that a, b, c are statements such that the implication if a, then b and not c is true. Use the rules of inference to determine the possible combination of truth values for the statements a, b and c. If a|bc, then a|b or a|c. (a) what is the converse of this statement? (b) for this statement and its converse, determine if they are true or false. Give appropriate proofs for your answers: let a, b z. Find an integer x such that a|x and b|x: suppose a, b and c are three statements. A = (b c) (a = b) (a = c).
