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 white counter and a red counter.
| Colour | Black | White | Red |
|---|---|---|---|
| Probability | 35\displaystyle \frac{3}{5}53 | 110\displaystyle \frac{1}{10}101 |
