What are Amy and Brittany?

What are Amy and Brittany?

### Hint

Guess and Check### Answer

Take Amy's statement and assume it's true. If Brittany is a knave, that means that she is lying. That would mean that one of them is a knave, which would still be true. If Amy was lying, then Brittany would be telling the truth that neither of them were knaves, which would contradict Amy's lie. Therefore, Amy is a knight, and Brittany is a knave.Hide Hint Show Hint Hide Answer Show Answer
