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.
A. 3/20
B. 0.15%
C. 17/20
D. 15%
To find the experimental probability that a unit will pass inspection, we need to determine the number of units that passed inspection out of the total 1,000 units.
Number of units that passed inspection = 1,000 - 150 = 850
Experimental probability of a unit passing inspection = Number of units that passed inspection / Total number of units
Experimental probability = 850 / 1000
Experimental probability = 17/20
Therefore, the correct answer is:
C. 17/20
