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}.
True Statement about Complement
- 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.
