On the Isle of Knights and Knaves, Knights always tell the truth, and Knaves always lie.However, it is not immediately obvious who is a Knight and who is a Knave. You encounterthree inhabitants, Albert, Betty, and Carla whom are each either Knights or Knaves. Notethat there are 8 possibilities.Albert says: "I'm a Knight, but I'm not the only Knight." Betty says: "Either Albert is aKnight or Carla is a Knight, but not both." Carla says: “Albert is Knave!"(b) There are 8 possibilities regarding who are Knight(s) and who are Knave(s). Identify allof the possibilities which are consistent with the above information.(c) Using Rules of Inference and Propositional Equivalences, formally prove your answer(s).

We will use the basics of mathematical logic to answer this question correctly.

Answered: (b) There are 8 possibilities regarding…
