Math
oh sorry about that.... (p V q) <---> (~r ^ p)

Math
Determine the truth value of the statement when p is t, q is f

Math-CONFUSING!!
Sweet!!! Thanks Max!!

Math-CONFUSING!!
So it's like this? (r ^ p) -> q

Math-CONFUSING!!
Write the compound statement in symbols. Let r = The food is good, p = I eat too much, q = I'll exercise. If the food is good and I eat too much, then I'll exercise.

Math-this 1 is confusing :(
okay...that makes a little more sense...thanks Max!

Math-this 1 is confusing :(
Given p is true, q is false, and r is false, find the truth value of the statement (q ^~r) ->~p.

Math-Please help :(
Construct a truth table for the statement. (p ↔ q) → p

Math
Okay....thanks :)

lol i know right!! i hate the truth tables too!! i think this is it: T T F F T T F F F T T F

Math
Construct a truth table for ~q ->(p V q)

Math
ooooooh okay i get it now lol thank you :)

Math
So it would be p q V ?? Because I have to fill in the heading (line) with any of those choices....

Math
Fill in the heading of the following truth table using any of p, q, ->, ?, V, and ^. P q _____ T T T T F F F T T F F T

great! thank u :)
