To find the percentage of parts that are not defective, we need to subtract the number of defective parts from the total number of parts and then divide by the total number of parts.
Let's break down the steps to solve this problem:
1. Find the number of non-defective parts:
Total number of parts - Number of defective parts = 500 - 5 = 495
2. Calculate the percentage of non-defective parts:
(Number of non-defective parts / Total number of parts) × 100
= (495 / 500) × 100
= 0.99 × 100
= 99%
Therefore, the correct answer is option C) 99%.
