It seems there was an issue with extracting the content of the image correctly. Let me adjust the extraction method and try again to capture the text.It appears that the text extraction from the image wasn't successful. I'll manually interpret the content of the image to solve the questions related to set theory.

Here are the details I can gather:

Sets:

• $A = \{ 2, 3, 7, 1, 0, 8, 4, 6, 5, 7 \}$
• $B = \{ 5, 6, 8, 9, 2 \}$
• $C = \{ 5, 3, 4, 6, 7 \}$
• $U = \{ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 \}$

Problems:

1. $A \cup B$
2. $A \cap C$
3. $A \setminus C$
4. $A \cap B$
5. $B \setminus C$
6. $n(C)$
7. $n(B \cap A)$
8. $(A \cup B)^\prime$
9. $A^\prime$
10. $(B \setminus C)^\prime$
11. $(A \setminus B) \cup (B \setminus C)$
12. $A \cap B$
13. $n(B)$
14. $B \cup C$
15. $(A \cup B) \setminus (B \cap C)$

I'll now proceed to solve these one by one.

Solutions:

1. $A \cup B$: Union of $A$ and $B$
2. $A \cap C$: Intersection of $A$ and $C$
3. $A \setminus C$: Difference between $A$ and $C$
4. $A \cap B$: Intersection of $A$ and $B$
5. $B \setminus C$: Difference between $B$ and $C$
6. $n(C)$: Cardinality of $C$
7. $n(B \cap A)$: Cardinality of $B \cap A$
8. $(A \cup B)^\prime$: Complement of $A \cup B$
9. $A^\prime$: Complement of $A$
10. $(B \setminus C)^\prime$: Complement of $B \setminus C$
11. $(A \setminus B) \cup (B \setminus C)$
12. $A \cap B$: Intersection of $A$ and $B$
13. $n(B)$: Cardinality of $B$
14. $B \cup C$: Union of $B$ and $C$
15. $(A \cup B) \setminus (B \cap C)$

I'll now calculate these answers.Here are the solutions to the set theory problems:

1. $A \cup B = \{0, 1, 2, 3, 4, 5, 6, 7, 8, 9\}$
2. $A \cap C = \{3, 4, 5, 6, 7\}$
3. $A \setminus C = \{0, 1, 2, 8\}$
4. $A \cap B = \{2, 5, 6, 8\}$
5. $B \setminus C = \{2, 8, 9\}$
6. $n(C) = 5$ (Cardinality of set $C$)
7. $n(B \cap A) = 4$ (Cardinality of $B \cap A$)
8. $(A \cup B)^\prime = \emptyset$ (Complement of $A \cup B$)
9. $A^\prime = \{9\}$ (Complement of set $A$)
10. $(B \setminus C)^\prime = \{0, 1, 3, 4, 5, 6, 7\}$
11. $(A \setminus B) \cup (B \setminus C) = \{0, 1, 2, 3, 4, 7, 8, 9\}$
12. $A \cap B = \{2, 5, 6, 8\}$
13. $n(B) = 5$ (Cardinality of set $B$)
14. $B \cup C = \{2, 3, 4, 5, 6, 7, 8, 9\}$
15. $(A \cup B) \setminus (B \cap C) = \{0, 1, 2, 3, 4, 7, 8, 9\}$

Feel free to ask if you need any clarifications or further details.
