 If {1,2,3,4,5,6,7,8} U is universal set. Let {1,2,4,6} A and {2,3,5,7} B be two 
subsets of U. Then, find bit string of A, B, c A , c B  A B  , A B  , c A B  , c B A  ,  c A B  , 
c c A B  and ( )c A 

Given that the universal set is \( U = \{1, 2, 3, 4, 5, 6, 7, 8\} \), we are asked to represent the sets \( A \), \( B \), and their complements and intersections in terms of **bit strings**. A bit string uses 0 or 1 to indicate the absence or presence of elements corresponding to their positions in the universal set.

Let’s break it down and find the bit strings for each set and operation:

### Step 1: Bit Strings for A, B, and Complements
- **Universal set \( U \)** has 8 elements, so the bit strings will be 8 bits long.
- **Set \( A = \{1, 2, 4, 6\} \)**:
    - \( A \) includes elements 1, 2, 4, and 6. In terms of a bit string, this is:  
      \( A = 11010100 \)  
    (1s at positions corresponding to 1, 2, 4, and 6, and 0s elsewhere).
  
- **Set \( B = \{2, 3, 5, 7\} \)**:
    - \( B \) includes elements 2, 3, 5, and 7. In terms of a bit string, this is:  
      \( B = 01101010 \)  
    (1s at positions corresponding to 2, 3, 5, and 7, and 0s elsewhere).

- **Complement of \( A \) (\( A^c \))**:
    - \( A^c \) includes all elements not in \( A \), which are \( \{3, 5, 7, 8\} \). The bit string for \( A^c \) is:  
      \( A^c = 00101011 \).
  
- **Complement of \( B \) (\( B^c \))**:
    - \( B^c \) includes all elements not in \( B \), which are \( \{1, 4, 6, 8\} \). The bit string for \( B^c \) is:  
      \( B^c = 10010101 \).

### Step 2: Set Operations
- **Union of \( A \) and \( B \) (\( A \cup B \))**:
    - The union includes elements that are in either \( A \) or \( B \). The bit string for \( A \cup B \) is:  
      \( A \cup B = 11111110 \).
  
- **Intersection of \( A \) and \( B \) (\( A \cap B \))**:
    - The intersection includes elements that are in both \( A \) and \( B \). The bit string for \( A \cap B \) is:  
      \( A \cap B = 01000000 \).
  
- **Union of complement of \( A \) and \( B \) (\( A^c \cup B \))**:
    - This operation includes elements that are in \( A^c \) or \( B \). The bit string for \( A^c \cup B \) is:  
      \( A^c \cup B = 01101011 \).
  
- **Union of complement of \( B \) and \( A \) (\( B^c \cup A \))**:
    - This operation includes elements that are in \( B^c \) or \( A \). The bit string for \( B^c \cup A \) is:  
      \( B^c \cup A = 11010101 \).
  
- **Union of complement of \( A \) and complement of \( B \) (\( A^c \cup B^c \))**:
    - This operation includes elements that are in \( A^c \) or \( B^c \). The bit string for \( A^c \cup B^c \) is:  
      \( A^c \cup B^c = 10111111 \).
  
- **Complement of intersection of \( A \) and \( B \) (\( (A \cap B)^c \))**:
    - The complement of the intersection is the set of elements not in \( A \cap B \). The bit string for \( (A \cap B)^c \) is:  
      \( (A \cap B)^c = 10111111 \).

### Summary of Bit Strings
1. \( A = 11010100 \)
2. \( B = 01101010 \)
3. \( A^c = 00101011 \)
4. \( B^c = 10010101 \)
5. \( A \cup B = 11111110 \)
6. \( A \cap B = 01000000 \)
7. \( A^c \cup B = 01101011 \)
8. \( B^c \cup A = 11010101 \)
9. \( A^c \cup B^c = 10111111 \)
10. \( (A \cap B)^c = 10111111 \)

4. Can you explain how to compute the complement of a union or intersection using De Morgan’s laws?
5. How does the universal set affect the length of bit strings?

**Tip:** The union of sets corresponds to the logical "OR" operation, while the intersection corresponds to the logical "AND" operation on bit strings.

If U = {1,2,3,4,5,6,7,8} is the universal set, let A = {1,2,4,6} and B = {2,3,5,7} be two subsets of U. Then, find the bit string of A, B, A^c, B^c, A ∪ B, A ∩ B, A^c ∪ B, B^c ∪ A, A^c ∪ B^c, and (A ∩ B)^c.
