Permutations- a counting technique where you want to pick r items from n items and the order of the r items is important. Ex: there are 9 players on a baseball team. They must be put in a batting order. Solution: this type of multiplication is called factorial. Suppose there are 12 people, on the baseball team. The coach needs to pick 9 of them to play in the game. How many ways can he schedule 9 players from the 12. Solution: 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 = 79, 833,600.
