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 probability that a unit will pass the inspection can be calculated as follows:
Number of units that passed inspection = Total units - Number of units rejected
Number of units that passed inspection = 1000 - 150 = 850
Empirical probability of passing inspection = Number of units that passed inspection / Total units
Empirical probability of passing inspection = 850 / 1000
Empirical probability of passing inspection = 0.85
Therefore, the approximate empirical probability that a unit will pass the inspection is 0.85 or 85%.
