Question
Let p and q be statements, and consider the following six statements.p ∧ ∼ q p ∨ q ∼ p ∧ q p → q q → p ∼ qDetermine the maximum number of these six statements that can be simultaneously true,and which truth values for p and q are needed to obtain this maximum. Explain yourreasoning.
Solution
To solve this problem, we need to consider all possible combinations of truth values for p and q. There are four possibilities: (p, q) = (T, T), (T, F), (F, T), (F, F).
-
(p, q) = (T, T): In this case, the statements p ∧ ∼ q, ∼ p ∧ q, and ∼ q are false, while the statements p ∨ q, p → q, and q → p are true. So, 3 out of 6 statements are true.
-
(p, q) = (T, F): In this case, the statements p ∧ ∼ q, p ∨ q, and p → q are true, while the statements ∼ p ∧ q, q → p, and ∼ q are false. So, 3 out of 6 statements are true.
-
(p, q) = (F, T): In this case, the statements ∼ p ∧ q, p → q, and q → p are true, while the statements p ∧ ∼ q, p ∨ q, and ∼ q are false. So, 3 out of 6 statements are true.
-
(p, q) = (F, F): In this case, the statements p → q, q → p, and ∼ q are true, while the statements p ∧ ∼ q, p ∨ q, and ∼ p ∧ q are false. So, 3 out of 6 statements are true.
In all four cases, the maximum number of statements that can be simultaneously true is 3. Therefore, the maximum number of these six statements that can be simultaneously true is 3, and this can be achieved with any truth values for p and q.
