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.

Answer 1

The number of units that passed the inspection is 1,000 - 150 = 850.
The empirical probability that a unit will pass the inspection is:
850/1,000 = 0.85 or 85% (rounded to two decimal places).
