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 = Total units inspected - Number of units rejected
= 1000 - 150
= 850
Total number of units inspected = 1000
Empirical probability = Number of units that passed inspection / Total number of units inspected
= 850 / 1000
= 0.85 or 85%
Therefore, the correct answer is 85%.

0.15%
17/20
1.5%
To find the empirical probability that a unit will pass the inspection, we need to calculate 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
= 1000 - 150
= 850
Total number of units inspected = 1000
Empirical probability = Number of units that passed inspection / Total number of units inspected
= 850 / 1000
= 17/20
Therefore, the empirical probability that a unit will pass the inspection is 17/20. So the answer is 3/20.
