Play Quality Control inspected 1000 yards 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 need to calculate the ratio of the number of units that passed the inspection to the total number of units inspected.
Number of units that passed = Total units inspected - Number of rejected units
Number of units that passed = 1000 - 150 = 850
Empirical probability that a unit will pass the inspection = Number of units that passed / Total units inspected
Empirical probability = 850 / 1000
Empirical probability = 0.85 or 85%
Therefore, the empirical probability that a unit will pass the inspection is approximately 85%.
