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..
To approximate the empirical probability that a unit will pass the inspection, we can calculate the proportion of units that passed the inspection out of the total number of units inspected.
Number of units that passed inspection = 1,000 - 150 = 850
Empirical probability of passing the inspection = Number of units that passed inspection / Total number of units inspected = 850 / 1,000 ≈ 0.85
Therefore, the approximate empirical probability that a unit will pass the inspection is 0.85 or 85%.
