The spinner is spun and lands with one of its edges on the ground.
5
- Assume that the spinner lands on each number with equal probability.
5
- State a distribution that could be used to model the number that the spinner lands on.
5
- (ii) Use your distribution from part 5
- to find the probability that the spinner lands on a number greater than 5

- Clare spins the spinner 1000 times and records the results in the following table.
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
| Frequency | 37 | 64 | 112 | 161 | 308 | 156 | 109 | 53 |
5 - Explain how the data shows that the model used in part (a) may not be valid.
