![### De Morgan's Laws: Statement Equivalence
Use De Morgan's laws to determine whether the two statements are equivalent:
1. \( q \rightarrow (p \land \neg r) \)
2. \( q \rightarrow (\neg p \lor r) \)
**Choose the correct answer below:**
- O The two statements are equivalent.
- O The two statements are not equivalent.
### Explanation
To determine whether the two logical statements are equivalent, we apply De Morgan's laws, which state:
- The negation of a conjunction is the disjunction of the negations:
\[
\neg (A \land B) \equiv (\neg A \lor \neg B)
\]
- The negation of a disjunction is the conjunction of the negations:
\[
\neg (A \lor B) \equiv (\neg A \land \neg B)
\]
Thus, we analyze both statements provided:
1. \( q \rightarrow (p \land \neg r) \)
2. \( q \rightarrow (\neg p \lor r) \)
By De Morgan's laws:
- The expression \( \neg (p \land \neg r) \equiv (\neg p \lor r) \)
Therefore, the expressions within the parentheses are indeed the negation of each other, thus transforming one statement into the other to check for equivalence. Upon applying these laws, we can determine whether the transformed statements hold the same truth values across all possible scenarios.
Please apply De Morgan's laws and logical equivalence rules to confirm the correctness of the transformation and whether the original statements are indeed equivalent.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F94f92ff5-1fee-41b2-9a69-3f1799cc23e2%2Fc70c43c9-823d-4b14-bb3d-9180bd646b60%2Fqj4ck0i_processed.jpeg&w=3840&q=75)
