A quality controller Inspected 1000 units of a product and rejected 150 units do today fix approximate the probability that a unit will pass inspection
To find the approximate probability that a unit will pass inspection, we can use the formula:
Probability of passing inspection = (Total units - Rejected units) / Total units
In this case, the total units inspected is 1000 and the number of units rejected is 150. Plugging these values into the formula:
Probability of passing inspection = (1000 - 150) / 1000
Probability of passing inspection = 850 / 1000
Probability of passing inspection = 0.85
Therefore, the approximate probability that a unit will pass inspection is 0.85 or 85%.
