A permutation is a way of rearranging items, a combination is a way of combining different items together. The formula uses factorials (the exclamation point). because that's the number of times we've counted each possibility. The Fundamental Counting Principle is also known as the Multiplication Principle in Combinatorics (8). Permutation and Combination. 4 Permutations The word 'permutations' means 'arrangements'. Because products of the form n (n -1) (n - 2) . = 6. Example 1: Claire has 2 2 shirts and 2 2 skirts of different colors in her closet. Then, we can calculate the total number of possible outcomes by multiplying the number of options at each stage. The fundamental counting principle says that if you have sets A and B with a and b elements, respectively, then there are a * b distinct pairs (x,y) with x from A and y from B. It's worth mentioning that the multiplication principle extends to more than pairs. There are many ways to answer each of the questions provided in this handout. 2.Under the fundamental principle of counting comes the principle of addition and the principle of multiplication.
