**MathMate**, Monday, July 9, 2012 at 2:22pmThe truth table for ~q is the opposite:

q ~q

T F

F T

The truth table for conditional, p→q is true except when p is true and q is false, i.e.

p q p→q

T T T

T F F

F T T

F F T

For p∧q, the result is true only if both are true, i.e.

p q p∧q

T T T

T F F

F T F

F F F

Based on the above, you should attempt the compound truth table. Post if you have questions or need to verify your result.

**MathMate**, Monday, July 9, 2012 at 2:24pmSorry, I gave the truth table for ∧ when it should be or, ∨, which is false only when both p and q are false, i.e.

p q p∨q

T T T

T F T

F T T

F F F
