   The PERMUTATION FORMULA The number of permutations of n objects taken r at a time:! P(n,r)= n! (n"r)! This formula is used when a counting problem involves both: 1. Choosing a subset of r elements from a set of n elements; and 2. Arranging the chosen elements. Referring to EXAMPLE 1.5.6 above, Gomer is choosing and arranging a subset of 9

   Here, we are counting the permutations of 6 different letters taken 3 at a time. The required number of words = 6 × 5 × 4 = 120 (by using multiplication principle). If the repetition of the letters was allowed, the required number of words would be 6 × 6 × 6 = 216.

   When order does not matter this is called a combination. How many possible ways are there to do this? The approach to nding a general rule is like the table example from the previous section. First let’s consider if the order did matter. Then it’s just P(5;3). However imagine now that certain permutations of kittens would be considered 3
