Answer:
The policy on deducting marks for a wrong answer but correct calculation may vary depending on the instructor or institution. In some cases, partial credit may be given for showing the correct method or steps, but arriving at the wrong final answer. In other cases, there may be no partial credit and the answer is either correct or incorrect. It's best to check with your instructor or refer to the grading policy of your institution for specific guidelines on how they grade exams or assignments.
