its 126 but i dont know how to get the answer Permutation notation (for your problem) would be _9 P _5 (_5 and _9 are like subscripts to the P), meaning "how many ways to choose 5 from 9 in a specific order". If you have a graphing calculator, you can use the permutation operation to find it (let me know if you do, so I can tell you where to find it). If not, here is the standard, "by-hand" method: _n P _r = (n!)/(n-r!). With your problem, that would be (9!)/(4!) = 15,120. HOWEVER, in your problem, the order of players chosen does not matter--only the final team does. Therefore, we use a combination (_n C _r), meaning (n!)/(r!)(n-r!). So, to answer your question, we plug in the values. (9!)/(5!)(9-5!) = 126. Your final answer is 126 ways.
