## What is a true or false question?

A true or false question consists of a statement that requires a true or false response. There are other variations of the True or False format as well, such as: “yes” or “no”, “correct” or “incorrect”, and “agree” or “disagree” which is often used in surveys.

## What is a true-false?

1. true-false – offering a series of statements each of which is to be judged as true or false; “a true-false test” multiple-choice – offering several alternative answers from which the correct one is to be chosen; or consisting of such questions; “multiple-choice questions”; “a multiple-choice test”

## Is true and false true?

True is written: true; False is written: false; Not is written in a variety of ways.

## What is true && false?

The && requires that both items are true – think of it as having two statements on either side (rather than just true or false itself). The && means, essentially: “Are BOTH of these statements true?” If the answer is yes, then it returns true. in any other case, it returns false.

## What is P and Q in truth table?

They are used to determine the truth or falsity of propositional statements by listing all possible outcomes of the truth-values for the included propositions. Given two propositions, p and q, “p and q” forms a conjunction. The conjunction “p and q” is only true if both p and q are true.

## What does P mean truth table?

p is true

## What is PV Q?

It means that either p is false or q is false or they are both false–anyway, p and q can’t both be true at the same time. So ~(p · q) º ~p v ~q. On the other hand, ~(p v q) means it’s not the case that either p or q. In other words, they ate both not true.

## Does every sentence have a truth value?

All statements (by definition of “statements”) have truth value; we are often interested in determining truth value, in other words in determining whether a statement is true or false. Statements all have truth value, whether or not any one actually knows what that truth value is.

## What is truth value example?

Truth Value For example, if the statement ‘She loves to chase squirrels’ is true, then the negative of the statement, ‘She does not love to chase squirrels,’ is false. Now, if the statement p is true, then its negation NOT p must be false, so we put F in the same row under the NOT p column.

## Do statements have to be true?

But the sentence expresses something that is either true or false. The same statement can be true on some occasions and false in others. That is, statements are not always true or always false.

## Which of the following is accepted to be true without proof?

Geometry Chapter 2-Part 1

A | B |
---|---|

Postulate | A statement that describes a fundamental relationship between the basic terms of geometry-Postulates are accepted as true without proof. |

Theorem | A statement or conjecture that can be proven true by undefined terms, definitions, and postulates |

## What do you call a statement that is always true?

Tautology: A statement that is always true, and a truth table yields only true results. Contradiction: A statement which is always false, and a truth table yields only false results.

## Can a mathematical statement be true before it has been proven?

So yes, mathematical statements are true before they have been proven. This is because it is not a theory just yet, they are all hypothesis, and all hypothesis are true until they have been tested. So therefore a mathematical statement is technically true before it has been proven as it is only a statement.

## What is a theorem in math?

Theorems are what mathematics is all about. A theorem is a statement which has been proved true by a special kind of logical argument called a rigorous proof.

## What is the sequence of statements that demonstrates that a theorem is true?

It consists of a set of assumptions (called axioms) linked by statements of deductive reasoning (known as an argument) to derive the proposition that is being proved (the conclusion). If the initial statement is agreed to be true, the final statement in the proof sequence establishes the truth of the theorem.
