Truth table 

how would solve this problem?

p ^ ~p =

p v~p

 

Expert Solution
Step 1

Let us construct the truth table for the given statement 

p ^ ~p

~ is called negation operator, that is ~p is true if and only if p is false and vice versa.

is called logical conjunction, the statement p and ~p  is true only if both are true, otherwise it is false.

 ~p p ^ ~p
T F F
F T F

If all the entries in the final column is false, then it is called as Contradiction.
