A bag contains counters of four different colours: purple, orange, white and black. The table shows the probabilities of picking a purple counter and a white counter at random.
| Colour | Purple | Orange | White | Black |
|---|---|---|---|---|
| Probability | 0.15 | 0.45 |
The probability of picking an orange counter is equal to the probability of picking a black counter.
Complete the table to show the probabilities of picking an orange counter and a black counter.
