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