A band has 25 new songs, how many different ways are there for the group to record a CD consisting of 12 songs chosen from 25 new songs. ( The order in which the songs appear on the CD is relevant).
DJ Jacqueline is making a playlist for an mp3 player; she is trying to decide what
songs to play and in what order they should be played. If she has her choices narrowed down to
hip-hop songs, and she wants to play an equal number of blues, reggae, and hip-hop songs, how many different playlists are possible? Express your answer in scientific notation rounding to the hundredths place.
