Quizplus · Accepted Answer

The correct answer is 50%, which is represented as choice B. This is because the question asks for the probability in a percentage form, not as a decimal or fraction. Therefore, 50% is the correct choice, and the other options either represent the percentage incorrectly or use a different format (like 0.50% which is actually 0.5%).
