Question

In a factory, a manager tests 250 products and finds defects in 7 of them. How many defects are likely going to be in a 10,000 unit order.

Answer 1

280

Explanation:

first make a proportion. 7 over 250= x over 10,000. cross multiply to get 250x=70,000. 70,000 divided by 250 which gets you 280.
