Fill in the blanks using the given Venn diagrams to identify set operations.

I'll solve this Venn diagram problem step by step. Let me first examine the image to understand what's being asked.

Looking at the image, I can see it's a worksheet titled "Venn Diagram - Two Circles" with three different Venn diagrams. For each diagram, I need to fill in the blanks using the given Venn diagrams by calculating set operations like union (A ∪ B), intersection (A ∩ B), difference (B - A), etc.

Let me start with the first Venn diagram (top one) which shows sets A and B.

For the first diagram:
- Set A contains: 1, 2, 4, 5
- Set B contains: 2, 3, 4, 6

Now I'll calculate each required operation:

1. A ∪ B (union of A and B): All elements that are in A or B or both
A ∪ B = {1, 2, 3, 4, 5, 6}

2. A ∩ B (intersection of A and B): Elements that are in both A and B
A ∩ B = {2, 4}

3. A - B (elements in A but not in B):
A - B = {1, 5}

4. B - A (elements in B but not in A):
B - A = {3, 6}

Let me move to the second Venn diagram (middle one) which shows sets C and D.

For the second diagram:
- Set C contains: 5, 6, 7, 8
- Set D contains: 6, 7, 9, 10

Calculating each operation:

1. C ∪ D (union of C and D): All elements that are in C or D or both
C ∪ D = {5, 6, 7, 8, 9, 10}

2. C ∩ D (intersection of C and D): Elements that are in both C and D
C ∩ D = {6, 7}

3. C - D (elements in C but not in D):
C - D = {5, 8}

4. D - C (elements in D but not in C):
D - C = {9, 10}

Finally, let me work on the third Venn diagram (bottom one) which shows sets E and F.

For the third diagram:
- Set E contains: 1, 2, 3, 4, 5
- Set F contains: 3, 4, 5, 6, 7

Calculating each operation:

1. E ∪ F (union of E and F): All elements that are in E or F or both
E ∪ F = {1, 2, 3, 4, 5, 6, 7}

2. E ∩ F (intersection of E and F): Elements that are in both E and F
E ∩ F = {3, 4, 5}

3. E - F (elements in E but not in F):
E - F = {1, 2}

4. F - E (elements in F but not in E):
F - E = {6, 7}

I've now solved all the problems on the worksheet. Let me summarize the answers:

First Diagram (Sets A & B):
- A ∪ B = {1, 2, 3, 4, 5, 6}
- A ∩ B = {2, 4}
- A - B = {1, 5}
- B - A = {3, 6}

Second Diagram (Sets C & D):
- C ∪ D = {5, 6, 7, 8, 9, 10}
- C ∩ D = {6, 7}
- C - D = {5, 8}
- D - C = {9, 10}

Third Diagram (Sets E & F):
- E ∪ F = {1, 2, 3, 4, 5, 6, 7}
- E ∩ F = {3, 4, 5}
- E - F = {1, 2}
- F - E = {6, 7}
