### How are the operations union and intersection different?

The union of two sets includes all elements from both sets, while the intersection includes only the elements that are common to both sets.

### What are the fundamental operations in set theory?

The fundamental operations in set theory are union, intersection, and complement.

### What does the complement of a set represent?

The complement of a set represents all the elements not in the set within a given universal set.

## Study Notes

### Set Theory Operations

• Union and intersection are two distinct operations in set theory:
• Union results in a set containing all elements from both sets, without repetition.
• Intersection results in a set containing only the common elements between the two sets.

### Fundamental Operations

• The fundamental operations in set theory are:
• Union (∪)
• Intersection (∩)
• Complement

### Complement of a Set

• The complement of a set represents all elements that are not in the set.
• The complement of a set A with respect to the universal set U contains all elements in U but not in A.

### Union of Sets

• The result of the union of sets A and B, denoted as A ∪ B, is a set containing all elements from both sets without repetition.

### Intersection of Sets

• The result of the intersection of sets A and B, denoted as A ∩ B, is a set containing only the common elements between the two sets.
• Example: If set A = {1, 2, 3} and set B = {3, 4, 5}, then A ∩ B = {3}.

• The statement "The complement of a set A with respect to the universal set U contains all elements in U but not in A" is true.
