A rock group needs to choose 3 songs to play at the annual Battle of the Bands. How many ways can they choose their
set if they have 15 songs to pick from? /(10 pts)

If they have 15 songs to choose from and they can only pick three, that means they might have 5 different ways of choosing those songs.

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
