Could anyone help me with HW 5.3

Suppose you have a 12 by 12 checkerboard with alternating brown and white squares. If 5 pieces are randomly placed on the checkerboard:
what is the probability that they will all be placed on white squares?
what is the probability that they will all be placed on squares of the same color?

Suppose that a playlist has 15 songs (all different) with 4 of the songs being by Laura Cantrell. If you listen to 4 songs in shuffle mode, what is the probability that you will hear at least one song by Laura Cantrell?
If you listen to 4 songs from this playlist on an mp3 player that has a "random" mode, what is the probability that you will hear at least one song by Laura Cantrell?
