this ones more complicated. my teacher says that you need to use all three symbols (conjunction, disjuncion, and not)
i swear if the answer to this one is as simple as the last one i posted im gonna kick myself
Use the symbols ^(conjunction), disjunction, and '(not) to form a sentence involving p and q whose truth table is given
p q ?
T T F
T F F
F T F
F F F
so make a sentence thatll make the truth table true

The output is always false. I don't know what you're supposed to use for disjunction, so will use "OR". Also I'm assuming the negation operator (') follows the term it applies to. So, the output is
(p^p') OR (q^q')
This uses all three operators.
p AND not-p is always false, and so is q AND not-q. So the OR of the two is also always false.

The first answer only involves p. The last one seems quite good.
