it is a problem of logic concerning who killed Julius Caesar.
I have written the logical sentences and build the truth table, but I cannot find a way to combine all these...
p: Marcus Antonius(says): Cassius or Brutus or both
q: Cassius(says): not me. Marcus Antonius is lying
r: Brutus(says): if I did it, then the other two are guilty also.
m: Marcus Antonius is guilty
c: Cassius is guilty
b: Brutus is guilty
A guilty person always lies.
A non-guilty person always tells the truth
p: c OR b OR (c AND b)
q: c’ AND m (because a guilty always lies)
r: b => (c AND m)
