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) Responses 0.15% 0.15% 1720 Start Fraction 17 over 20 End Fraction 320 Start Fraction 3 over 20 End Fraction 1.5%
To find the empirical probability that a unit will pass the inspection, we need to divide the number of units that passed by the total number of units inspected.
Number of units that passed = Total units inspected - Number of units rejected
Number of units that passed = 1000 - 150
Number of units that passed = 850
Empirical probability that a unit will pass the inspection = Number of units that passed / Total units inspected
Empirical probability that a unit will pass the inspection = 850 / 1000
Empirical probability that a unit will pass the inspection = 0.85 or 85%
Therefore, the approximate empirical probability that a unit will pass the inspection is 85%.
