Question 1120433: on your phone you have 23 rap songs and 14 country songs. How many 6 song playlists (order matters) can you make that have 4 rap and 2 country songs Answer by greenestamps(13200) (Show Source):
I will assume "order matters" means the 6 different songs, and not just 4 rap and 2 country songs. In that case, the 6 songs can be arranged in 6!=720 different orders.
Then the number of ways you can choose 4 of the 23 rap songs is 23C4 = 8855 and the number of ways you can choose 2 of the 14 country songs is 14C2 = 91.
