There are many such methods: cluster sampling, stratified random sampling, simple random sampling.Their usefulness depends on the circumstances.
Answer is Quota sampling. Its one of the method of non-probability sampling.
Simple random sampling.

advantage of probability sampling
In probability sampling,every item in the population has a known chance of being selected as a member.In non-probability sampling, the probability that any item in the population will be selected for a sample cannot be determined.

Sampling techniques in researching involves to types of sampling. The probability sampling and the non-probability sampling. Simple random is an example of probability sampling.

the difference is just that non-probability sampling does not involve random selection, but probability sampling does.
Non probability sampling and probability sampling are different because probability sampling uses random samples. Non probability sampling aren't random, but can still be representative of the population as a whole if done correctly.
In probability sampling,every item in the population has a known chance of being selected as a member.In non-probability sampling, the probability that any item in the population will be selected for a sample cannot be determined.
Non probability sampling is where the samples are not selected randomly.
One of the best non-probability sampling methods is purposive sampling, also known as judgmental sampling. This method involves selecting participants based on specific characteristics or criteria relevant to the research question, ensuring that the sample is well-suited to provide insights into the topic. It allows researchers to focus on specific subgroups, making it particularly useful in qualitative research where depth of understanding is prioritized over generalizability. However, it's essential to acknowledge that findings from purposive sampling may not be representative of the broader population.
The two main types of sampling are probability sampling and non-probability sampling. Probability sampling involves selecting samples in a way that each member of the population has a known chance of being chosen, ensuring that the sample is representative. Non-probability sampling, on the other hand, does not provide all individuals in the population with a known or equal chance of selection, which can lead to biases in the sample. Common methods include random sampling for probability sampling and convenience or purposive sampling for non-probability sampling.
Random sampling is a method of selecting a sample where each member of the population has the same probability of being included in the sample. An equivalent statement is that each subset of the population, of the given size, has the same probability of being selected as any other subset of that size.
