How many of them are from the tribe that always lie?
The first one has to be lying. If he speaks the truth, he contradicts himself.
The second one could be right, as both others would be lying. This is a valid answer.
If the last one is telling the truth, he claims two are lying, one of them the man who said two were lying who would be speaking the truth.
So, there are two who lie.
