A computer user has downloaded 22 songs using an online file-sharing program and wants to create a CD-R with 11 songs to use in his portable CD player. If the order that the songs are placed on the CD-R is not important to him, how many different CD-Rs could he make from the 22 songs available to him? There are possible CD-R's.​

The answer would be 484

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
