I'm having trouble solving this problem. If you could help I would be grateful.
Mr. Kaplen's class needs to choose 4 students out of 24 to be on committee. How many different groups can be selected?
--------------
The 1st choice is 1 of 24, then 1/23, 1/22, 1/21
--> 24*23*22*21 = 255,024
---------
If there's no difference in the 4 positions, then choosing A,B,C&D is the same as B,D,A,C so there are 24 ways (4*3*2*1) to choose the 4.
----
255024/24 = 10,626 ways
