6. Use a truth table to determine whether or not each of the following pairs of sentences are tautologically (TT) equivalent. (i) AɅ (BVC) (AAB) V (AAC) (ii) (PAQ) VR PA (QVR) For a satisfactory answer do the same five things (a) -(e) from Qu. 2 above, except that the verdict in each case will be either 'TT equivalent' or 'Not TT equivalent'. ABCAA (BVC) (AAB) V (A^ C) PQR (PAQ) VR PA (QVR) Are they TT equivalent? Is there a counter-example row? (Mark all such rows with a *.) Are they TT equivalent? Is there a counter-example row? (Mark all such rows with a *.)
3. How to express the associativity of V as a tautology?
Use the truth table test of validity to determine whether the following arguments are valid or invalid. To be invalid, the premises will be true, but the conclusion false. INSTRUCTIONS: 1. First, identify and define the type of Truth Functional Connective each symbol represents and type it in to the first table. 2. Then, create a Formal Method Test of validity table below each argument to determine whether the argument is valid or invalid. 3. Indicate whether the argument is valid or invalid. If the argument is invalid, highlight the area on the table that proves it. A row for each possible outcome [2"] → Use the pattern of half the rows to make half of the values in the column true → For the next column keep using the pattern of half Remember to Create: Type in the meaning of the symbol in the space provided.
