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
The experimental probability that a unit will pass inspection can be found by dividing the number of units that passed inspection by the total number of units:
Number of units that passed inspection = Total number of units - Number of units rejected
Number of units that passed inspection = 1000 - 150 = 850
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%.
Can you do it in fractions
Sure!
The experimental probability that a unit will pass inspection in fraction form is:
Number of units that passed inspection = Total number of units - Number of units rejected
Number of units that passed inspection = 1000 - 150 = 850
Therefore, the experimental probability in fraction form is:
850 / 1000
This fraction can be simplified by dividing numerator and denominator by their greatest common divisor, which is 50:
850 ÷ 50 = 17
1000 ÷ 50 = 20
So, the experimental probability that a unit will pass inspection in simplified fraction form is:
17 / 20
