    the upside down v is the conjunction and the right arrow is the conditional

    Can you figure out the truth value of NOT r (~r) and q AND p (q^p)?

    it dosent say, it just wants to know whether its a true or false statement, no numbers involved.

    so you're not familiar with conjunctions?

    I am somewhat, but I keep getting the darn things wrong. I know that ~r is a false statement, so thats true, not sure about q, but I think ~p is the same as r...

    the conjunctions and disjunctions change everything up

    ` let r represent a false statement` so `~r` would be true `~r` is the complete opposite of `r`

    `q ^ p` would be false because while q is true, p is false both need to be true in order for `q ^ p` to be true otherwise, `q ^ p` is false

    so by majority, the overall statement would be false?

    yes that's correct. The overall conditional is false
