Question

A quality-control center finds that 2 out of 250 toy trains are defective. How many trains would they expect to be defective in a batch of 10,000?
A.80

B.40

C.250

D.125

Answer 1

Its A. 10,000 divided by 250 is 40. Then multiply 40 by 2 and you get 80

10,000 / 250 = 40 
40 * 2 = 80
80= A.
