Answer:
The expected value for the number of inspections until a defective unit is found 17.
Step-by-step explanation:
Percentage of defective microchips = 6%
Let the total number of inspection = x
number of defective microchip = 1
As we know
1/x = 6%
1/x = 0.06
x = 1/ 0.06
x = 16.67 inspections
x = 17 ( rounded off to nearest whole number )
17 inspection is done until the defective microchip is found.
( 3 × 4 ) ÷ 2
then multiply that by 11
