# MATH 140 - Lecture 4 Worksheet

## 1. Make a truth table for the following statement:

### (a) \( \neg(P \lor Q) \lor (\neg P) \)

### (b) "The product \( xy = 0 \) if and only if \( x = 0 \) or \( y = 0 \)"

### (c) \( P \lor (Q \land \neg R) \)

---

In this worksheet, you are tasked with creating truth tables to analyze the logical statements provided. Each statement involves logical operators such as negation (\(\neg\)), conjunction (\(\land\)), and disjunction (\(\lor\)). By organizing the truth values systematically for each proposition, you will gain a better understanding of how these logical expressions function under various conditions.
