To approximate the empirical probability that a unit will pass the inspection, we need to find the proportion of units that passed the inspection out of the total units inspected.
Number of units that passed inspection = Total units inspected - 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 inspected
Empirical probability of passing inspection = 850 / 1000
Empirical probability of passing inspection = 0.85 or 85%
Therefore, the correct response is 85%.
