Experimental probability is calculated by dividing the number of times the event occurred by the total number of opportunities for the event to occur.
In this case, the event is a unit passing inspection, and it occurred 1000 - 150 = 850 times out of the total 1000 units inspected.
Therefore, the experimental probability that a unit will pass inspection is 850/1000 = 0.85, or 85%.
A quality controller inspected 1000 units of a product and rejected 150 units due to defects find the experimental probability that a unit will pass inspection
