selecting all the students that have a last name that begins with R
selecting all the girls
putting all the names in a hat and selecting six students
putting all the names in alphabetical order and selecting every fourth student

Answer 1

Putting the names in a hat and selecting six students

Answer 2

Putting all the names in a hat and selecting six students because the rest would not have been random because you know who you picked just by looking but if u put names in a hat you don't know who you picked.
