A ballet company has 30 dancers. They want to randomly sample 8 dancers to complete a survey. Select the three ways the company could create a valid random sample.

A. Take a spinner with 30 equal-sized sections and assign each dancer to a section. Spin the spinner 8 times to determine which dancers to survey.

B. At the next rehearsal, select the first 8 dancers to arrive at rehearsal to complete the survey.

C. Create a list of dancers numbered 1 through 30. Use a random number generator to select 8 random numbers from 1 to 30 that represent the dancers to survey.

D. Write the names of all dancers on equal-sized pieces of paper. Mix them up and draw 8 without looking to determine which dancers to survey.

Which of the symbols correctly relates the two numbers below check all that apply 6? 6
