The correct Answer is:
To solve the problem, we need to analyze the sets defined in the question and perform the required operations on them. Let's break it down step by step. ### Step 1: Define the Sets 1. **Set \( Z_N \)**: This is the set of non-negative integers, which includes \( \{0, 1, 2, 3, \ldots\} \). 2. **Set \( Z_P \)**: This is the set of non-positive integers, which includes \( \{ \ldots, -3, -2, -1, 0\} \). 3. **Set \( Z \)**: This is the set of all integers, which includes both positive and negative integers, as well as zero. 4. **Set \( E \)**: This is the set of even integers, which includes \( \{ \ldots, -4, -2, 0, 2, 4, \ldots\} \). 5. **Set \( P \)**: This is the set of prime numbers, which includes \( \{2, 3, 5, 7, 11, \ldots\} \). ### Step 2: Analyze Each Option #### Option 1: \( E \cap P \) - **Intersection of even integers and prime numbers**: The only even prime number is \( 2 \). - Therefore, \( E \cap P = \{2\} \). - This is not an empty set, so this option is incorrect. **Hint**: Check for common elements between the two sets. #### Option 2: \( Z_N \cap Z_P \) - **Intersection of non-negative integers and non-positive integers**: The only integer that is both non-negative and non-positive is \( 0 \). - Therefore, \( Z_N \cap Z_P = \{0\} \). - This is a singleton set, so this option is incorrect. **Hint**: Identify elements that belong to both sets. #### Option 3: \( Z - Z_N \) - **Subtracting non-negative integers from all integers**: This means we are left with negative integers, which is \( Z_P \). - Therefore, \( Z - Z_N = Z_P \). - This option is correct. **Hint**: Understand what remains after removing a subset from a larger set. #### Option 4: Symmetric Difference \( Z_N \Delta Z_P \) - **Symmetric difference**: This is defined as \( (Z_N \cup Z_P) - (Z_N \cap Z_P) \). - **Union of \( Z_N \) and \( Z_P \)**: This includes all integers (both positive and negative). - **Intersection of \( Z_N \) and \( Z_P \)**: As established, this is \( \{0\} \). - Therefore, the symmetric difference is \( Z - \{0\} \), which is all integers except \( 0 \). **Hint**: Remember that symmetric difference includes elements that are in either set but not in both. ### Conclusion After analyzing all options, we find that: - Option 1 is incorrect. - Option 2 is incorrect. - Option 3 is correct. - Option 4 is also correct. Thus, the correct answer is that Option 3 and Option 4 are valid, but since the question seems to imply a single answer, we conclude with Option 3 being the most straightforward correct answer. ### Final Answer **Option 3: \( Z - Z_N = Z_P \)** is correct.
