hello

they ask me to find the values for this statement

(~pvq) -> (pv~q)

for this stament I got as answer 3 true values and 1 false values, is that right?

they also ask me to find out whether this stament is a tautology

[(p->~q)^q]->~p

i got as answer that this is not a tautology

finally they ask me to by using morgan laws translate the following statement into a statement that means the same thing.

The exam was easy and I studied all night.

my answer is

I studied all night then the exam was easy.

thank you.
