Question

A manufacturer inspects 500 personal video players and finds that 497 of them have no defects. The manufacturer sent a shipment of 2,000 video players to a distributor. Predict the number of players in the shipment that are likely to have no defects.

Answer 1

Use proportion to solve:
$\frac{500 total}{497 good} = \frac{2000 total}{x}$
500x = (497)(2000)
      x = 1988

Answer: 1,988 players are likely to have no defect.
