Answer 1

A random selection procedure gives each individual an equal chance of being chosen. Examples include randomly selecting students and using a computer to generate random numbers.

Step-by-step explanation:

A random selection procedure is one in which each individual in a population has an equal chance of being chosen. Examples of random selection procedures include:

1. A computer program randomly selects 100 students from the alphabetical listing of all high school students and includes every 50th student until 75 students are selected.
2. A completely random method is used to select 75 students from the fall semester, where each student has the same probability of being chosen at any stage.
3. A computer generates 100 random numbers and chooses 100 people whose names correspond with the numbers on the list.
