The probability that a unit will pass the inspection can be calculated by subtracting the number of rejected units from the total number of units inspected and then dividing by the total number of units inspected:
(1000 - 150) / 1000 = 850 / 1000 = 0.85
Multiplying by 100 to convert to percentage gives 0.85 * 100 = 85%.
Therefore, the approximate empirical probability that a unit will pass the inspection is 85%.
