I suppose a DJ wants to select 4 different songs, then there are: 12*11*10*9 = 11880 ways to choose them.

If the order of the songs he plays doesn't matter, there are: [tex] \frac{12 * 11 * 10 *9 }{4!} = 495 [/tex] ways to choose them.

Answer:

The answer is NOT 495 WAYS (for when choosing 5) !!!! The CORRECT answer is 792!!!!!

>>>495 may be the answer "when choosing (four)"

UPDATE: This is the answer for when "choosing FIVE" not FOUR.
