A quality controller inspected 1,000 units of a product and then rejected 150 of those units due to defects. What is the approximate empirical probability that a unit will pass inspection? A 17/20, B 0.15%, C 1.5% or D 3 out of 20
To find the empirical probability that a unit will pass inspection, we need to divide the number of units that passed inspection by the total number of units inspected.
Number of units that passed inspection = 1000 - 150 = 850
Total number of units inspected = 1000
Empirical probability = Number of units that passed inspection / Total number of units inspected
= 850 / 1000
= 17/20
Therefore, the approximate empirical probability that a unit will pass inspection is A) 17/20.
