A quality controller inspected 1,000 units of a project and rejected 150 units due to defects. what is the empirical probability that a unit will pass inspection
To find the empirical probability that a unit will pass inspection, we need to determine the number of units that passed inspection out of the total number inspected.
Number of units that passed inspection = Total units inspected - Number of units rejected
Number of units that passed inspection = 1000 - 150 = 850
Now, we can calculate the empirical probability that a unit will pass inspection by dividing the number of units that passed inspection by the total number of units inspected:
Empirical probability = Number of units that passed inspection / Total units inspected
Empirical probability = 850 / 1000
Empirical probability = 0.85
Therefore, the empirical probability that a unit will pass inspection is 0.85 or 85%.
