Answer
# Brief Explanations:
Random sampling involves selecting a subset of individuals from a population in a way that each individual has an equal chance of being chosen. In this case, an overhead - picture of a part of the crowd is taken, which is a form of randomly selecting a sample of the crowd to estimate the total number. Stratified sampling divides the population into subgroups (strata) and samples from each stratum. Systematic random sampling selects elements at regular intervals. Cluster sampling divides the population into clusters and samples some of the clusters. Here, since a random part of the crowd is selected without dividing into strata, intervals, or clusters, it is random sampling.
# Answer:
random sampling.
