1)  You are given

    p q 
    T T

    which means p= T  and  q= T.

    You need to find  (=to calculate) a logic expression "q and not p".


     From the given, you have  q= T   and  "not p" = F  ====>  hence,  (q and not p) = (T and F) = (you must know it if you work on such problems) = F.



2)  You are given

    p q 
    T F

    which means p= T  and  q= F.

    You need to find  (=to calculate) a logic expression "q and not p".


     From the given, you have  q= F   and  "not p" = F  ====>  hence,  (q and not p) = (F and F) = (you must know it if you work on such problems) = F.



3)  You are given

    p q 
    F T

    which means p= F  and  q= T.

    You need to find  (=to calculate) a logic expression "q and not p".


     From the given, you have  q= T   and  "not p" = T  ====>  hence,  (q and not p) = (T and T) = (you must know it if you work on such problems) = T.



Thus, I gave some instructions/ideas/examples to you on how to do these simple calculations.


I leave it to you to complete the last #4 case on your own.


After completing it, you may submit your answer to the forum - we will check it (at no charge . . . ).
