Quizplus · Accepted Answer

The probability that a pair of hose is irregular is 1 - 0.92 = 0.08
Therefore, the expected number of irregular pairs produced per day is:
0.08 x 300000 = 24000
The question asks for the average number of non-irregular pairs available for the catalog order department, which is simply:
300000 - 24000 = 276000
Therefore, the best choice is C) 24000.
