A quality controller inspected 1,000 units of a product and and rejected 150 units due to defects. Approximate the empirical probability that a unit will pass that inspection.
To approximate the empirical probability that a unit will pass inspection, we need to divide the number of units that passed inspection by the total number of units inspected.
Number of units that passed inspection = 1000 - 150 = 850
Total number of units inspected = 1000
Empirical probability of a unit passing inspection = 850/1000 = 0.85
Therefore, the empirical probability that a unit will pass inspection is approximately 0.85.
To approximate the empirical probability that a unit will pass the inspection, we need to divide the number of units that passed the inspection by the total number of units inspected.
Number of units that passed the inspection = Total number of units inspected - Number of units rejected = 1000 - 150 = 850.
Empirical probability that a unit will pass the inspection = Number of units that passed the inspection / Total number of units inspected = 850 / 1000 = 0.85.
Therefore, the approximate empirical probability that a unit will pass the inspection is 0.85 or 85%.
