Truth tables: (p -> ~r) v (~q -> r)

[cnrep32]

I really don't understand truth tables and I need to know them for my take home test. Can somebody please help???

(p -> ~r) v (~q -> r)
---------
And this one that asks to determine if the statement: ~(q v r) v p is logically equivalent to the statement: ~ p -> (~r ^ ~ q)

Thank you!!!

Where are you stuck?

use the fact: p > q = ~p v q I used to mix up this equivalence all the time in my head, thinking it was "and" instead of "or". double check that, it if it's correct, i can help you further!
