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 getting a red counter.
| Colour | Red | Blue | White |
|---|---|---|---|
| Probability | 0.2 |
The probability of getting a blue counter is the same as the probability of getting a white counter.
Complete the table.
There are 18 red counters in the bag.
Work out the total number of counters in the bag.
