Each variable can be T or F (true or false). Since there are two variables with two truth values each, there are four possible combinations of truth values for both. I used all four combinations of T and F to make the first two rows of the table. Using the meaning of negation and "and", you construct the table one step at a time. First, p and q, then ~p and ~q, then ~p^~q, then its negation. By making the table one step at a time, you avoid any errors in calculating the truth values.
 
You may notice that the last row of the table yields the same truth values as p or q.
 
Let me know if you need further help or explanation on this.
