The logical expression involves the following statements or propositions: p, q, r.
The logical expression is: (p or q) or (not p or not r).
For 3 statements, there will be 8 rows in the truth table.
The possible truth values combinations for the statements are:
(False, False, False)
(False, False, True)
(False, True, False)
(False, True, True)
(True, False, False)
(True, False, True)
(True, True, False)
(True, True, True)
Evaluating the logical expression for each row:
Given {'p': False, 'q': False, 'r': False}, the expression evaluates to True.
Given {'p': False, 'q': False, 'r': True}, the expression evaluates to True.
Given {'p': False, 'q': True, 'r': False}, the expression evaluates to True.
Given {'p': False, 'q': True, 'r': True}, the expression evaluates to True.
Given {'p': True, 'q': False, 'r': False}, the expression evaluates to True.
Given {'p': True, 'q': False, 'r': True}, the expression evaluates to True.
Given {'p': True, 'q': True, 'r': False}, the expression evaluates to True.
Given {'p': True, 'q': True, 'r': True}, the expression evaluates to True.
The complete truth table is as follows:
| p | q | r | Result |
|+|+|+|+|
