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.
Complete the table.
Sarah is going to spin the spinner 200 times.
Work out an estimate for the number of times the spinner will land on 2.
