The image shows the following logical statement:

\[
\neg(p \land q) \rightarrow \left[ \left( \neg(p \land q) \lor r \right) \rightarrow q \right]
\]

This expression can be analyzed using propositional logic.

Here’s a breakdown:
1. The expression \(\neg(p \land q)\) represents the negation of \(p \land q\), i.e., it is true when either \(p\) or \(q\) (or both) are false.
2. The implication \(\rightarrow\) means "if...then."
3. The second part \(\left( \neg(p \land q) \lor r \right) \rightarrow q\) says "if \(\neg(p \land q)\) or \(r\) is true, then \(q\) must be true."

Would you like a step-by-step truth table to evaluate whether this formula is a tautology or valid in certain cases?

Here are 5 related questions you might explore:
1. What is the truth table for this logical expression?
2. How can De Morgan’s law simplify \(\neg(p \land q)\)?
3. How would this expression change if we used exclusive or (\(\oplus\)) instead of logical or (\(\lor\))?
4. Is this a tautology, contradiction, or satisfiable formula?
5. How can logical equivalence be applied to transform this expression?

**Tip**: When solving propositional logic problems, drawing a truth table is a great way to ensure you understand how each component behaves in different scenarios.

Prove or analyze the logical statement: \neg(p \land q) \rightarrow [(\neg(p \land q) \lor r) \rightarrow q]

Learn how to evaluate the logical statement \neg(p \land q) \rightarrow [(\neg(p \land q) \lor r) \rightarrow q]. This involves the use of negation, conjunction, disjunction, and implication in propositional logic. The problem explores De Morgan's laws, truth table analysis, and logical implications.
