The probability that a unit will pass the inspection can be calculated by taking the number of units that pass (1000 - 150 = 850) and dividing it by the total number of units inspected (1000).
850 / 1000 = 17/20
Therefore, the empirical probability that a unit will pass the inspection is 17/20.
A quality controller inspected 1,000 units of a product and rejected 150 units due to defects. Approximate the empirical probability that a unit will pass the inspection.
3/20
1.5%
0.15%
17/20

I apologize for the mistake in my previous response. Let me recalculate the probability.
Given that out of 1000 units inspected, 150 were rejected due to defects, the number of units that passed the inspection is 1000 - 150 = 850 units.
The empirical probability that a unit will pass the inspection is calculated as:
Number of units that passed inspection / Total number of units inspected
Therefore, the probability is:
850 / 1000 = 0.85
So, the correct answer is:
0.85
