- Subsets and
We are to check which of the given options is incorrect.
Analysis
- . This is correct.
- . This is correct.
- . This is correct.
- . Therefore, . This is correct.
Answer: None of the statements are incorrect.
Question 07
Given:
- Universal set
- Subsets and such that:
Find the sum of all elements of .
Solution
-
Using , these elements belong to but not . Therefore:
