To determine which types of sampling involve using random procedures to select a sample, we need to analyze each option:

1. Judgement sampling: This type of sampling does not involve random procedures. Instead, it relies on the judgement of the researcher or expert to select participants based on their knowledge or expertise. Therefore, judgement sampling does not involve random procedures.

2. Probabilistic sampling: This type of sampling does involve random procedures. It aims to ensure that each member of the population has an equal chance of being selected for the sample. Examples of probabilistic sampling methods include simple random sampling, stratified random sampling, and cluster sampling.

3. Subjective sampling: This term is not commonly used in the context of sampling methods. However, based on the given options, it is safe to assume that subjective sampling does not involve random procedures. It likely refers to a sampling method that relies on subjective criteria or personal preferences to select participants, rather than randomization.

4. Convenience sampling: Similar to judgement sampling, convenience sampling does not involve random procedures. It involves selecting participants who are readily available or easily accessible. This method is often used for its convenience, but it may introduce bias into the sample.

In summary, the types of sampling that involve using random procedures to select a sample are probabilistic sampling.
