Answer:

By using permutations

The number of ways to listen to four CDs from a selection of 8 CDs.

= $8_{P_{4} }$

we know that

$n_{P_{r} } = \frac{n!}{(n-r)!}$

$8_{P_{4} } = \frac{8!}{(8-4)!} = \frac{8 X 7 X 6 x 5 X 4!}{4!} = 1680$

The number of ways to listen to four CDs from a selection of 8 CDs = 1680
