In a bag there are only black counters, white counters and red counters. A counter is taken at random from the bag. The table shows the probability of taking a black counter and a white counter.
| Colour | Black | White | Red |
|---|---|---|---|
| Probability | 310\displaystyle \frac{3}{10}103 | 35\displaystyle \frac{3}{5}53 |
Complete the table to show the probabilities of the counter being red.
