To calculate 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 number 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 = Number of units that passed inspection / Total units inspected
Empirical probability = 850 / 1000 = 0.85
Expressing this as a percentage, the approximate empirical probability that a unit will pass the inspection is 85%. So, none of the provided responses accurately represent the empirical probability.
