A qualified controller expected $1,000 units of a product and reject the 150 units due to defects find the experimental probability that a unit will pass inspection a 3/20 b0.15% c 17 over 20 D 15%
To find the experimental probability that a unit will pass inspection, we need to divide the number of units that passed inspection by the total number of units.
Total units expected = 1000 units
Units rejected = 150 units
Number of units that passed inspection = 1000 - 150 = 850 units
Experimental probability = Number of units that passed inspection / Total units expected
Experimental probability = 850 / 1000
Experimental probability = 17 over 20
Therefore, the experimental probability that a unit will pass inspection is 17 over 20 or option c.
