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