Final answer:
To find the percentage of defective items in the lot, divide the number of defective items by the total number of items and multiply by 100. In this case, the percentage of defective items is 6%.
Step-by-step explanation:
To find the percentage of defective items in the lot, you need to divide the number of defective items by the total number of items and then multiply by 100.
In this case, there are three defective items out of a lot of 50 items. So, to find the percentage, you would divide 3 by 50 and then multiply by 100.
Percentage of defective items = (3 / 50) * 100 = 6%
