The correct Answer is:
To solve the problem, we need to analyze the two statements given: 1. **Statement I:** \( A \cup (B \cap C) = (A \cap B) \cup (A \cap C) \) 2. **Statement II:** \( A \cap (B \cup C) = (A \cup B) \cap (A \cup C) \) We will check the validity of each statement step by step. ### Step 1: Analyze Statement I We need to check if \( A \cup (B \cap C) = (A \cap B) \cup (A \cap C) \). **Left Side:** - \( A \cup (B \cap C) \) means we take all elements in set A and all elements that are in both B and C. **Right Side:** - \( (A \cap B) \cup (A \cap C) \) means we take all elements that are both in A and B, and all elements that are both in A and C. To see if these two sides are equal, we can use a Venn diagram or logical reasoning: - The left side includes all elements from A and any elements that are common to both B and C. - The right side includes elements that are in A and also those that are in both B and C. After analyzing, we can see that these two expressions are not equal. Thus, **Statement I is incorrect.** ### Step 2: Analyze Statement II Next, we check if \( A \cap (B \cup C) = (A \cup B) \cap (A \cup C) \). **Left Side:** - \( A \cap (B \cup C) \) means we take all elements that are in A and also in either B or C. **Right Side:** - \( (A \cup B) \cap (A \cup C) \) means we take elements that are in either A or B and also in either A or C. Again, we can analyze: - The left side includes elements that are in A and also in either B or C. - The right side includes elements that are in A, or in B, and also in A, or in C. Through logical reasoning or using a Venn diagram, we can show that these two expressions are indeed equal. Thus, **Statement II is correct.** ### Conclusion - **Statement I is incorrect.** - **Statement II is correct.** Therefore, the answer to the question is that only the second statement is correct. ### Final Answer Only Statement II is correct.
