To find the experimental probability that a unit will pass inspection, we need to calculate the ratio of the number of units that passed inspection to the total number of units inspected.
Number of units that passed inspection = Total units inspected - Number of units rejected
Number of units that passed inspection = 1000 - 150 = 850
Experimental probability that a unit will pass inspection = Number of units that passed inspection / Total units inspected
Experimental probability = 850 / 1000 = 17/20
Therefore, the correct response is: 17/20
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.(1 point)
