In a bag there are only red counters, blue counters and white counters. A counter is taken at random from the bag. The table shows the probability of the counter being red and blue.
| Colour | Red | Blue | White |
|---|---|---|---|
| Probability | 0.6 | 0.3 |
Complete the table to show the probability that counter will be white.
Hence work out the probability that the counter will be red or white.
