A quality controller inspected 1,000 units of a product and rejected 150 units due to defects. Find the experimental probability that a unit will pass inspection
3/20
0.15%
17/20
15%
The experimental probability that a unit will pass inspection is the number of units that passed inspection divided by the total number of units inspected.
Number of units that passed inspection = 1000 - 150 = 850
Total number of units inspected = 1000
Experimental probability = 850/1000 = 17/20 = 0.85 = 85%
Therefore, the correct answer is 17/20 or 85%.
