FALSE: **A valid argument must have a true conclusion only if all of the premises are true**. So it is possible for a valid argument to have a false conclusion as long as at least one premise is false.

## Can an argument be valid without premises?

**A deductive argument is said to be valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false**. Otherwise, a deductive argument is said to be invalid.

## Can a conclusion be true if the premises are false?

Because this argument relies on a false premise, it can be considered logically unsound. However, this doesn’t mean that the conclusion of the argument is necessarily false, since **even fallacious arguments can have true conclusions**, which means that it’s possible that it did indeed just rain.

## Is an argument valid if the conclusion is true?

Valid: an argument is valid if and only if it is necessary that **if all of the premises are true, then the conclusion is true**; if all the premises are true, then the conclusion must be true; it is impossible that all the premises are true and the conclusion is false.

## How do you determine if an argument is valid or invalid?

Think hypothetically. **Ask, “IF the premises are true, are we locked into the conclusion?” If yes, then the argument is valid.** **If no, then the argument is invalid**.

## Can argument be without conclusion?

**If a valid argument has a false conclusion, then at least one premise must be false**. TRUE: A valid argument cannot have all true premises and a false conclusion. So if a valid argument does have a false conclusion, it cannot have all true premises. Thus at least one premise must be false.

## Can an invalid argument have true premises and true conclusion?

**Invalidity is a no guarantee of a true conclusion when the premises are true**. True premises can lead to either a true or a false conclusion in an invalid argument. In these examples, luck rather than logic led to the true conclusion.

## What is a valid argument form?

An argument form is valid **if, no matter what particular statements are substituted for the statement variables in its premises, whenever the resulting premises are all true, the conclusion is also true**. (Hint: If any premises are false, then the argument is vacuously true.)

## When an argument is valid and its premises are true the argument is called?

More specifically, we ask whether the argument is either deductively valid or inductively strong. A **deductive argument** is an argument that is intended by the arguer to be deductively valid, that is, to provide a guarantee of the truth of the conclusion provided that the argument’s premises are true.

## What makes an argument valid example?

A valid argument is an argument in which **the conclusion must be true whenever the hypotheses are true**. In the case of a valid argument we say the conclusion follows from the hypothesis. For example, consider the following argument: “If it is snowing, then it is cold. It is snowing.

## Does every invalid argument form have valid instances?

An invalid argument form is one that does have substitution instances with true premises and a false conclusion. The conclusion is false in lines 2 and 4. In each of these lines, there is also a false premise. **Since there is no substitution instance with true premises and a false conclusion, the argument form is valid**.

## What is argument and argument form?
