I have a question regarding a version of the truthtellers and liars puzzle which I haven't seen anywhere before.
I'm stranded on an island and I know that this island has cannibals, but I don't know how to distingush between who are cannibals and who aren't. I run into three people on the island, A,B,C, and I ask them: "How many of you are truthtellers?" And A responds "flop flip" in his own native language. I then ask what it means, and B then says "It means only one" whereafter C says: "Don't trust B she is lying. Come with me I'm not a cannibal." How do I know what to do?
I want to set this up in a truth table, but I don't know how to formalize "only one of us is a truthteller" into logic.
