Answer 1

Answer:

1995 players have no defects.

Step-by-step explanation:

A manufacturer inspects a sample of 400 personal video players and finds that 399 of them have no defects.

The ratio of non-defective video players = $\frac{399}{400}$

If the manufacturer send a shipment of video players to a distributor = 2000

The number of players are likely to have no defects. =   $\frac{399}{400}$ × 2000 = 1995

1995 of the players are likely to have no defects.

Answer 2

Lets look at the info we have:-

400 personal video players and find that 399 have NO defects. 

Solve:-

2000 ÷  400 = 5

So, about 5 of the video players will be defect.
