If you are on the student council you need a b average you are not on student council therefore you do not have a b average

A:valid
B:invalid

The argument is valid.

The statement is valid.

The argument presented is valid. Here's why:

To determine the validity of an argument, we need to assess the logical structure of the argument rather than the truth of the premises. In this case, the argument follows a logical conditional "if-then" structure:

1. If you are on the student council, then you need a B average.
2. You are not on the student council.

Based on these premises, the conclusion is drawn:

3. Therefore, you do not have a B average.

The argument is valid because the conclusion follows logically from the premises. It doesn't matter whether the premises or the conclusion are true in reality; as long as the logical structure is valid, the argument is valid.

Please note that the truth or accuracy of the premises or the conclusion should be assessed separately from the logical validity of the argument.
