The quality control team has raised concerns about the quality of the output of a specific machine being used in your pilot test. You ask the team to provide quantitative data to validate their concerns. The quality control team leader reports that on average 9 of 375 articles produced by the specific machine are defective. What is the probability that an article chosen at random will be defective?
- 3/125
- 1/41
- 1/9
- 0.24
The correct answer is A.
Answer A is correct because the quality control team has identified a 9/375 chance of error. This can be mathematically simplified by reducing the fraction to its common denominator, resulting in a 3/125 chance that a randomly chosen article will be defective.
