A biased spinner can land on 1, 2, 3 or 4.
The table shows the probabilities that the spinner will land on 2 and 4.
| Number | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
| Probability | 0.35 | 0.20 |
The probability that the spinner will land on 1 is twice the probability that the spinner will land on 3.
