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
Experimental probability is calculated by dividing the number of successful outcomes by the total number of outcomes. In this case, the successful outcome is a unit that passes inspection, which is 1,000 units minus the 150 rejected units, or 850 units.
Therefore, the experimental probability that a unit will pass inspection is:
850 successful units / 1,000 total units = 0.85
So, the experimental probability that a unit will pass inspection is 0.85 or 85%.
