Explanation:
Detailed explanation-1: -In a class of 45 students, 33 are boys. What is the percentage of girls in the class? If 33 are boys, 45–33=12 are girls. Therefore, the percentage of girls is 100*12/45 = 26.67%.
Detailed explanation-2: -Simple random sampling. In simple random sampling (SRS), each sampling unit of a population has an equal chance of being included in the sample. Consequently, each possible sample also has an equal chance of being selected.
