Answer: a) 3 sqdroot (2) B) 12

Explanation: Explanation is in the picture. There is an easier way to solve this which is to factor the 6. The factors would be 3 and 2. Because there are two pairs of 3s (sqdroot 3 x sqdroot 3x2), 3 will go out of the sqdroot while 2 stays in it.

A disc jockey wants to select 4 songs from a new cd that contains 12 songs. How many ways can the disc jockey choose four songs?

WARRIOR [948]

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: $\frac{12 * 11 * 10 *9 }{4!} = 495$ ways to choose them.
