## How do you verify a truth table?

To verify the truth table of a logic gate, the suitable IC is taken and the connections are given using the circuit diagram. For all the ICs, 5V is applied to the pin 14 while the pin 7 is connected to the ground. The logical inputs of the truth table are applied and the corresponding output is noted….

## What makes an argument valid or invalid?

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. If this is possible, the argument is invalid.

## Can an argument be valid but have false premises?

A valid argument can have false premises; and it can have a false conclusion. But if a valid argument has all true premises, then it must have a true conclusion. Since a sound argument is valid, it is such that if all the premises are true then the conclusion must be true.

## Can an invalid argument be true?

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. If an invalid argument has all true premises, then the conclusion must be false.
