The empirical probability of a unit passing the inspection can be estimated by taking the number of units that passed the inspection divided by the total number of units inspected.
Number of units that passed the inspection = 1000 - 150 = 850
Total number of units inspected = 1000
Empirical probability = 850/1000 = 0.85
Therefore, the approximate empirical probability that a unit will pass the inspection is 0.85 or 85%.
a quality controller inspected 1,000 units of a product and rejected 150 units due to defects Approximate the empirical probiblity that a unit will pass the inspection
