Case 283
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Ruby: “The guilty person is either Mila or Finn.”
Theo: “Ruby is guilty.”
Mila: “The guilty person is either Ruby or Jade.”
Finn: “Neither Theo nor Finn is guilty.”
Jade: “Neither Mila nor Jade is guilty.”
Random case Solution: Ruby is guilty. Testing each possible culprit leaves this as the only assignment where the culprit's statement is false and all four innocent statements are true.
