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.
• 0.15%
• 17/20
• 3/20
• 1.5%
The empirical probability of a unit passing the inspection can be calculated by taking the number of units that passed (1,000 - 150 = 850) and dividing it by the total number of units inspected (1,000).
So, the empirical probability of a unit passing the inspection is:
850/1000 = 0.85 or 85%
Therefore, none of the given answer choices are correct. The closest one is 1.5%, which is actually the percentage of units rejected due to defects.
