You are tutoring a friend of yours who is enrolled in an introductory statistics class. They are struggling with the concept of methods of counting. Create and solve an assessment question that will test your friend on calculating a permutation, an arrangement, and a combination.
Note: You can create (and solve) three individual questions (1, 2, and 3) OR create a scenario and ask three questions about it (a, b, and c). Your questions must be unique and cannot be plagiarised from the course material or from other sources.
