Final answer:
The boolean expression (a || b) || !(a || b) evaluates to True.
Step-by-step explanation:
The boolean expression (a || b) || !(a || b) evaluates to True. In the expression, (a || b) represents the logical OR operation between variables a and b. If either a or b (or both) is true, the result will be true. Then, the ! operator is applied to the result of (a || b), which negates the outcome. Since (a || b) is true, ! (a || b) will be false.
