A compound proposition is said to be satisfiable if there is an assignment of truth values to its variables that makes it true. For example, pnq is true when p-T and q-T, thus, p q s satisfiable. When no such assignment exists, the compound proposition is said to be unsatisfiable. For example, p is always false, thus, is unsatisfiable. To show that a compound proposition is satisfiable, we need to find at least one assignment of truth values to its variables that makes it true. However, to show that a compound proposition is unsatisfiable, we need to show that every assignment of truth values to its variables makes it false. 6.
