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 0.15 1.5 3/20 or 17/20
The empirical probability that a unit will pass the inspection is calculated by taking the number of units that passed the inspection divided by the total number of units inspected.
Number of units that passed the inspection = Total units - Number of units rejected = 1000 - 150 = 850
Empirical probability = Number of units that passed the inspection / Total units inspected = 850 / 1000 = 0.85
Therefore, the correct answer is 17/20.
