Math Problem Statement
Construct truth tables for the following statements: i.(p →~p) ∨(p→q):
Solution
Let's construct the truth table for the logical statement:
(p → ¬p) ∨ (p → q)
Steps:
- Break the statement into components:
- (negation of )
- (implication)
- (implication)
- (disjunction)
Truth table:
T | T | F | F | T | T |
T | F | F | F | F | F |
F | T | T | T | T | T |
F | F | T | T | T | T |
Explanation:
- : This is true only when is false, as a true proposition cannot imply its own negation.
- : This is true when either is false, or when both and are true.
- : The disjunction of these two implications is true whenever at least one of the implications is true.
Result:
The truth table shows that the overall statement is only false when and .

p → q (Implication: False only when p is True and q is False)
¬p (Negation of p)
p ∨ q (Disjunction: True if at least one of p or q is True)
Theorems
Truth table rules for implication: p → q is false only when p is true and q is false.
Disjunction (p ∨ q) is true if at least one of p or q is true.
