Question

A light bulb manufacturer randomly tests 1500 bulbs and finds that 2 are defective.


How many defective bulbs would be expected in a shipment of 24,000 bulbs?

A.
32

B.
48

C.
120

D.
750

Answer 1

A. 32, because 1500/2 = 750 you would divide 1500 by 2 because only 2 were found defective or that would also mean that one in every 750 didn't work. Sooo you would divide 750 by 24000 (24000/750) to get your answer 32.

Answer 2

well if 2 are defective in 1,500 then do 1,500 / 2 = 750 Then do 24,000/750 = 32
