Can a false statement be true?
A true-false statement is any sentence that is either true or false but not both. A negation of a statement has the opposite meaning of a truth value. If we call the statement: cucumbers are green, p then: p: cucumbers are green – this statement is true.
Does false mean not true?
When someone says something is false, it has only a value of -1. When someone says something is not true, it can have a value not only of -1, but also of 0. Therefore, not true (0, -1) is not the same as false (-1).
Can statements be true and false at the same time?
The same statement can be true on some occasions and false in others. That is, statements are not always true or always false. Here’s an example: I’m a Kiwi.
Can a truth value be true and false?
In classical logic, with its intended semantics, the truth values are true (denoted by 1 or the verum ⊤), and untrue or false (denoted by 0 or the falsum ⊥); that is, classical logic is a two-valued logic. This set of two values is also called the Boolean domain.
What is a statement that is either true or false?
Definition: Statements are the kind of sentences that are either true or false. As such, a statement is an assertion that something is or is not the case. A statement is true if what it asserts is the case, and it is false if what it asserts is not the case. For instance, the statement “The trains are always late” is only true if what it describes is the case, i.e., if it is actually the case that the trains are always late.
What statement is always false?
A propositional statement that is always true is called a tautology, while a propositional statement that is always false is called a contradiction. For instance, the statement “I will eat my dinner or I will not” is a tautology, because it allows for either instance and therefore is always true.
Which of the statements is false?
A false statement is a statement which is factually untrue. When someone makes such a statement, however, it is not made with the intent to mislead, which distinguishes it from a lie.
Is a claim a statement that is true or false?
A claim is merely a statement expressing a belief. If that statement is true, it can be used as a reason to support a conclusion within an argument, if false, it cannot (the conclusion is a claim, as well).
