Process (How to do the activity)
Solution : Combination, because 9 selected CDs the order does not matter.
 * 1) A music CD library offers a choice of 9 CDs 	from a list of 60. In how many ways can a member make a selection?
 * 2) Permutations, because the order of the CDs 		selected does matter.
 * 3) Combinations, because the order of the 		CDs selected does not matter.


 * 1) One hundred people purchase lottery tickets. 	Three winning tickets will be selected at random. If first prize is 	$100, second prize is $50, and third prize is $10, in how many 	different ways can the prizes be awarded?
 * 2) Permutations, because the order of the 		selected winning tickets does matter. 
 * 3) Combinations, because the order of the 		selected winning tickets does not matter.

Solution : Permutations, because 3 prizes are different – as they have different amount of money and the order in this case matters.
