What does the unison symbol (AUB) indicate?

• A. The intersection of sets A and B
• B. The union of sets A and B
• C. The complement of set A
• D. The difference between sets A and B

Answer: (B)

The unison symbol, represented as \( A \cup B \), signifies the union of sets A and B. The union of two sets includes all elements that are in set A, in set B, or in both sets. This means that if an element is present in either of the sets, it will be included in the union. For example, if set A contains the elements {1, 2, 3} and set B contains the elements {3, 4, 5}, the union \( A \cup B \) will consist of {1, 2, 3, 4, 5}. Notice that the element '3', which is common to both sets, appears only once in the union. This property of unions is what helps to combine distinct elements from both sets without duplication, thereby providing a comprehensive collection of all unique elements from both sets A and B.
