Q4 Nomanisan Island 10 Points On Nomanisan Island, the natives communicate only person to person. Each inhabitant belong to one of two tribes: T or F. When two people from the same tribe communicate, they tell the truth, but when two people from different tribes communicate, they lie. You meet 3 inhabitants, denoted A, B, C, and you ask them to talk about who is from what tribe. You observe these statements: A to B:C is from tribe T and B from F. B to C:A is from tribe F or C from T. C to A:B is from tribe F if and only if A is from tribe F. Q4.2 Simplify what C says to A 1 Point I presume that for what what C said to A you created an expression like (CA)(BA) , which must be true if the rules of the island hold. Simplify this expression so it uses only two of the three variables. (Here, the expression is enough; you can explain your steps in Q4.4. Symbols to copy: )
