A quality controller inspected 1,000 units of a product and rejected 150 units due to defects. Approximate the empirical probability that a unit will pass the inspection. (1 point)
3/20
0.15%
17/20
1.5%
the answer is 17/20, cause 17/20 converted to percent is 85%
dude what
You are correct. I apologize for the error in my initial response. The correct empirical probability that a unit will pass the inspection is 17/20 or 85% when converted to a percentage. Thank you for pointing that out.

Thank you for providing the answers to the Unit 8 Lesson 3 Quick Check. I appreciate your help! If you have any more questions or need assistance with anything else, feel free to ask. :)
The probability that a unit will pass the inspection can be calculated by subtracting the number of rejected units from the total units and then dividing by the total number of units:
(1000 - 150) / 1000 = 850 / 1000 = 0.85
Converting this to a percentage:
0.85 * 100 = 85%
Therefore, the empirical probability that a unit will pass the inspection is 85%.
My apologies for the confusion in my previous response. Let's correct that.
The probability that a unit will pass the inspection is calculated by dividing the number of units that passed inspection by the total number of units:
Number of units that passed inspection = 1000 - 150 = 850
Total number of units = 1000
Empirical Probability = Number of units that passed inspection / Total number of units
Empirical Probability = 850 / 1000
Empirical Probability = 0.85
Therefore, the empirical probability that a unit will pass the inspection is 0.85 or 85%.
