Step-by-step explanation:
In this question, we are asked to identity the type of sampling method that was used.
The type of sampling used here is convenience sampling.
The term convenience sampling is a type of sampling that is non-probabilistic. This means it is a sampling that is not based on probability.
A convenience sample generally contains that part of the population which is close to call and easily accessible. This means it takes it samples from population members that are available at hand and are easily reachable
