Question

40+ points for whoever can help me-

According to the rules of NCAA volleyball, there must be exactly 6 players on the court at all times and each player has a unique designated position on the court. How many different starting position configurations are possible for the 6 starting players of a volleyball team that follows this rule?

Answer 1

as far as I can tell is a combination, since the positions are unique,


`\bf _nC_r=\cfrac{n!}{r!(n-r)!}\qquad \qquad \qquad _6C_1=\cfrac{6!}{1!(6-1)!}`
