construct a truth table for the statement. ∼ (∼p ∧ ∼q)

OpenStudy (anonymous):

method or just answer? usually start with p q t t t f f t f f

OpenStudy (anonymous):

so ~p and ~q ~p ~q f f f t t f t t

OpenStudy (anonymous):

for (~ p and ~q) they both must be true, so get (~p and ~q) f f f t

OpenStudy (anonymous):

and finally to negate this flip the f and t to get ~(~p and ~q) t t t f

OpenStudy (anonymous):

which as you see is the same truth table for p or q. they are the same.

OpenStudy (anonymous):

Its a bit easier to read when they are all lined up

OpenStudy (anonymous):

IE shows it as a single line of text
