Let P (x) denote the statement x >7.. However, note that this discussion is a considerable oversim-plication, Solution: The truth tables for these compound propositions are displayed in Table 3.Because the truth values of the compound propositions (p q) and p q agree for all possible combinations of the truth values of p and q, it follows that(p q) (p 2. why do we use predicate logic? Predicate logic uses quantifiers to indicate if a statement is always true, if it is sometimes true, or it is never true. In this sense, the quantifiers are used to correspond words such as all, some, never, and related expressions. 1. Solution: is (Question) What a beautiful picture!
