Propositional logic- mathematics Question: (*) A propositional formula A(p_1,..., p_n) of atoms p_1,.., p_n is called a parity check formula if all its models are exactly those interpretations that satisfy an even number of atoms among p_1, ..., p_n. Find parity check formulas which contain exactly one occurrence of each atom. Use connectives defined in the lectures. Write down your explanations. Hint: try n=1; n=2 and generalise from n-1 to n.
