Answer 2

1995 players have no defects.

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 =
`(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. =
`(399)/(400)` × 2000 = 1995

1995 of the players are likely to have no defects.
