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

To find the empirical probability that a unit will pass the inspection, we need to calculate the proportion of units that passed the inspection from the total number of units inspected.

Number of units that passed inspection = Total number of units inspected - Number of units rejected
Number of units that passed inspection = 1000 - 150 = 850

Empirical probability that a unit will pass the inspection = Number of units that passed inspection / Total number of units inspected
Empirical probability that a unit will pass the inspection = 850 / 1000 = 0.85 or 85%

Therefore, the empirical probability that a unit will pass the inspection is approximately 0.85 or 85%.
