The table shows the probabilities that a biased dice will land on 1, on 2, on 3, on 5 and on 6.
| Number | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|
| Probability | 0.12 | 0.18 | 0.09 | 0.16 | 0.2 |
The dice is rolled 250 times.
Work out an estimate for the number of times the dice will land on 2 or on 4. Hence work out an estimate for the number of times the dice will not land on 2 or on 4.
