Final answer:
A compound Boolean expression with the OR operator is true if either of its subexpressions is true. The correct option is b).
Step-by-step explanation:
A compound Boolean expression created with the OR operator is true if either of its subexpressions is true. The logic behind the OR operator allows for the possibility of both conditions being satisfied or just one, ensuring the expression evaluates to true in either case.
For example, in the context of a search, using artificial intelligence OR machine learning in a query will result in sources that contain either term or both, broadening the scope of the search. In contrast, the AND operator requires both conditions to be true to evaluate the expression as true, while the NOT operator negates the truth value of the single operand it precedes.
The exclusive use of these operators can significantly alter the outcome of the search results or logical expressions in various contexts, including database queries and programming conditional statements. Understanding these operators and their application is essential for efficient information retrieval and accurate logical reasoning.
