Truth Tables
1. The problem is to construct complete truth tables for the given logical statements involving propositions P, Q, and R.
2. Define the propositions:
- P: Policies are implemented effectively.
- Q: Public funds are managed properly.
- R: The community benefits from the government program.
3. The statements to analyze are:
1. ~P (negation of P)
2. ~Q (negation of Q)
3. P ^ ~Q (P and not Q)
4. P ^ Q (P and Q)
5. (~P ^ ~Q) V α (alpha is unspecified, so we consider it as a variable or constant to be defined; assuming α as an extra proposition)
6. (P ^ Q) V [(~P ^ ~Q) V Q]
4. For truth tables, list all possible truth values of P and Q (assuming R is not directly involved in these expressions).
Number of rows for the truth table with two variables (P, Q) is $2^2 = 4$.
5. Construct the truth table step by step:
| P | Q | ~P | ~Q | P ^ ~Q | P ^ Q | ~P ^ ~Q | ( ~P ^ ~Q ) V α | (P ^ Q) V [(~P ^ ~Q) V Q] |
|---|---|----|----|--------|--------|---------|----------------|--------------------------|
Fill the columns:
Row 1: P= T, Q= T
~P= F, ~Q= F
P ^ ~Q= T ^ F= F
P ^ Q= T ^ T= T
~P ^ ~Q= F ^ F= F
Assuming α as T or F is unknown; treat α as variable.
(~P ^ ~Q) V α= F V α= α
(P ^ Q) V [(~P ^ ~Q) V Q]= T V [F V T]= T V T= T
Row 2: P= T, Q= F
~P= F, ~Q= T
P ^ ~Q= T ^ T= T
P ^ Q= T ^ F= F
~P ^ ~Q= F ^ T= F
(~P ^ ~Q) V α= F V α= α
(P ^ Q) V [(~P ^ ~Q) V Q]= F V [F V F]= F V F= F
Row 3: P= F, Q= T
~P= T, ~Q= F
P ^ ~Q= F ^ F= F
P ^ Q= F ^ T= F
~P ^ ~Q= T ^ F= F
(~P ^ ~Q) V α= F V α= α
(P ^ Q) V [(~P ^ ~Q) V Q]= F V [F V T]= F V T= T
Row 4: P= F, Q= F
~P= T, ~Q= T
P ^ ~Q= F ^ T= F
P ^ Q= F ^ F= F
~P ^ ~Q= T ^ T= T
(~P ^ ~Q) V α= T V α= T
(P ^ Q) V [(~P ^ ~Q) V Q]= F V [T V F]= F V T= T
6. Interpretations:
- ~P and ~Q are negations of P and Q
- Conjunction (^) is AND
- Disjunction (V) is OR
7. Summary: The truth table allows evaluation of the statements under all truth assignments for P and Q.
Note: Since α is undefined, exact final values for statement 5 depend on α's truth value.
Final answer: Truth tables constructed according to above details with consideration of α as variable.
