method or just answer? usually start with p q t t t f f t f f
so ~p and ~q ~p ~q f f f t t f t t
for (~ p and ~q) they both must be true, so get (~p and ~q) f f f t
and finally to negate this flip the f and t to get ~(~p and ~q) t t t f
which as you see is the same truth table for p or q. they are the same.
