Question

A cell phone company checks a shipment of 200 phones and finds that 5 are defective. Based on this data, about how many defective phones should the company expect to be defective in a shipment of 760 phones?

Answer 1

Answer:

20

Step-by-step explanation:

There are 15 in 600. There would then be 2.5 for 100, but we round that to 3. There are 1 per every 40 in 200, so we have 19. We have 20 left, and could expect at least one, so it is 20. :)
