who lies? (propositional logic)

who lies? (propositional logic)

Postby yuu00 » Mon Oct 14, 2019 8:44 pm

A says B&C tell the truth
B says A tell the truth
C says A lies and B tells the truth

A's.satement.is.true B's C's
A T T F
B T T T -> B tells the truth
C T T

I have to use propositional logic to make out who lies and who tells the truth. I got to B telling the truth, but it all seems to contradict
