Question

State the number of possibilities: you select 4 people to represent your class of 205 students

Answer 1

If you have 205 students, and only 4 open positions, there would be multiple possibilities. For this question I would multiply 4 by 205, in which would contain every single possibility. 4 positions, 205 students, 4 times 205 would be 820 possibilities. Hope this helps.
