The polling methods likely to be biased are:
- **Five of Janine's friends are selected and asked for whom they intend to vote.**
This method is biased because it involves selecting a non-representative sample of voters (Janine's friends), who may have a stronger bias towards supporting her, leading to skewed results.
The method of selecting "every 10th club member from a list of all members" is less likely to be biased, as it uses a systematic sampling approach that includes a broader range of club members. However, biases can still occur depending on the list's order and the initial selection process, so it's not truly free from bias, but it's generally a more neutral method compared to the first option.
