Nonprobability sampling does not involve random selection of participants from a sampling frame, so statistical formulas cannot be used to determine the appropriate sample size. Instead, the sample size for nonprobability samples is usually determined based on the researcher's subjective judgment and practical constraints, such as time and budget limitations. Therefore, option E is the correct choice.
