Question 84169
Since there are 5 students to choose from, and a "team" consists of 4 players, you are taking a combination of "5 students taken 4 at at time".  One way to write this is C(5,4).  To find the value of this:
{{{(5*4*3*2)/(4*3*2*1) }}}
={{{5}}}.


An easier way to do this is to realize that CHOOSING 4 out of 5 to be on the team is EXACTLY the same as choosing 1 out of 5 to NOT be on the team.  There are obviously 5 ways to choose 1 person NOT to be on the team, so the answer is 5.
