Air quality controller inspected 1000 years of product and rejected 150 units due to defect. Find the experimental probability that a unit will pass infection.

Answer 1

First, calculate the total number of units that passed inspection:
Total units = 1000 - 150 = 850 units

Next, calculate the experimental probability that a unit will pass inspection:
Experimental probability = Number of units that passed inspection / Total number of units
Experimental probability = 850 / 1000
Experimental probability = 0.85

Therefore, the experimental probability that a unit will pass inspection is 0.85 or 85%.
