Step 1: Construct a truth table for the expression p (p q). We need columns for p, q, p q, and p (p q). Step 2: Fill in the truth values for all possible combinations of p and q. Recall that p q is true if at least one of p or q is true. Recall that p r is false only when p is true and r is false; otherwise, it is true. |c|c|c|c| p & q & p q & p (p q) \\ T & T & T & T \\ T & F & T & T \\ F & T & T & T \\ F & F & F & T \\ Step 3: Examine the final column for p (p q). All the truth values in the column for p (p q) are 'T' (True). Since the expression p (p q) is true for all possible truth values of p and q, it is a tautology. That's 2 down. 3 left today — send the next one.
