Erin's CD changer holds 6 compact disks. Justin uses the random function on to play all the songs randomly. If each of the disks on the changer holds 10 songs, what is the probability has favorite song will be first?
If I am getting the hang of this, it's 1/2160
I don't know how you got 1/2160. There are only 60 possibilities, and the favorite is one of them = 1/60.
I hope this helps. Thanks for asking.
