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
The proportion of units that passed the inspection can be calculated by subtracting the number of rejected units from the total number of units:
1000 units - 150 rejected units = 850 units passed the inspection
The empirical probability that a unit will pass the inspection is calculated by dividing the number of units that passed by the total number of units inspected:
850 units passed / 1000 units inspected = 0.85
Therefore, the approximate empirical probability that a unit will pass the inspection is 0.85 or 85%.
