I will love and rate 5.0 if done correctly with no images and no trolling for answer.

A hardware store receives shipments containing 600 light bulbs each. A sample of 75 light bulbs in a given shipment contains 3 that are defective. What is the sample ratio of defective light bulbs to total light bulbs in the shipment written as a percent?

A - 4%
B - 10%
C - 20%
D - 76%


Answer :

The correct answer should 4% because the ratio is 3 out of 75 which would leave 72 non-defective bulbs. So your answer is 4%
