Please do not copy answers from Chegg, I have seen all, they are wrong. I need an expert to do it in the correct way. I want to learn how to solve such problems. Thank You.

99 Here we have another islander problem as in Problem 1.6.9. There are three islanders: A says "If B and I are both telling the truth, then so is C", B says "If C is telling the truth, then A is lying", and C says "It is not the case that all three of us are telling the truth. Using propositional variables a, b, and c to represent the truth of the statements of A, B, and C respectively, we can represent the problem by the three premises a + ((a V b) + c), bH (c + -a), and c H -(a Ab Ac). Determine the conclusion as a conjunction of three literals, and give a deductive sequence proof of this conclusion from the premises. 99 Here we have another islander problem as in Problem 1.6.9.
