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. (1 point)
To find the empirical probability that a unit will pass the inspection, we need to calculate the number of units that passed the inspection out of the total number of units inspected.
Number of units that passed = 1,000 - 150 = 850
Empirical probability of passing the inspection = Number of units that passed / Total number of units inspected
= 850 / 1,000
= 0.85
Therefore, the approximate empirical probability that a unit will pass the inspection is 0.85 or 85%.
IS THAT 17/20?
Yes, you are correct. The empirical probability of a unit passing the inspection can also be represented as a fraction:
850 units passed inspection out of 1,000 inspected units.
So, the fraction can be simplified as:
850/1,000 = 17/20
Therefore, the approximate empirical probability of a unit passing the inspection is 17/20.
