A Quality controller inspected 1000 units of a product and rejected 150 units due to defects approximately the empirical probability that a unit will pass the inspection.
To find the probability that a unit will pass the inspection, we need to calculate the proportion of units that passed the inspection out of the total number of units inspected.
Number of units passed the inspection = 1000 - 150 = 850
Probability of passing the inspection = Number of units passed the inspection / Total number of units inspected
Probability of passing the inspection = 850 / 1000
Probability of passing the inspection = 0.85
Therefore, the empirical probability that a unit will pass the inspection is approximately 0.85 or 85%.
