A quality controller inspected 500 units of a product and rejected 80 units due to defects. What is the probability that a unit will pass inspection ( no defects)?
84%
50%
0%
16%
The probability that a unit will pass inspection (no defects) can be calculated by subtracting the number of rejected units from the total units inspected and then dividing by the total units inspected.
Number of units that passed inspection = Total units - Rejected units = 500 - 80 = 420
Probability = Number of units that passed inspection / Total units inspected = 420/500 = 0.84
Therefore, the probability that a unit will pass inspection (no defects) is 84%.
So the correct answer is 84%.
Are you sure
I apologize for the confusion in my response. Let me recalculate the probability:
Number of units that pass inspection = Total units - Rejected units = 500 - 80 = 420
Probability = Number of units that pass inspection / Total units inspected = 420/500 = 0.84
The correct probability that a unit will pass inspection (no defects) is indeed 84%.
So, the correct answer is 84%.
