A disc jockey has 12 songs to play. Seven are slow songs, and five are fast songs. Each song is to be played only once. In how many ways can the disc jockey play the 12 songs if
The songs can be played in any order.
The first song must be a slow song and the last song must be a slow song.
The first two songs must be fast songs.
WHAT IN THE WORLD DO I DO??

The first thing you need to do is proofread your post.
You state that the first song must be a slow song. Yet in the next sentence you say that the first two song must be fast.
Which is it?

Well its saying IF:
*The songs can be played in any order.
*The first song must be a slow song and the last song must be a slow song.
*The first two songs must be fast songs.
