The empirical probability that a unit will pass the inspection can be calculated by taking the number of units that passed the inspection divided by the total number of units inspected.
Number of units that passed = Total number of units inspected - Number of units rejected
Number of units that passed = 1000 - 150 = 850
Empirical probability = Number of units that passed / Total number of units inspected
Empirical probability = 850 / 1000 = 0.85
Therefore, the approximate empirical probability that a unit will pass the inspection is 0.85 or 85%.
