1 It follows that there are n! possible permutations of n distinct objects. 2. 2 n n! 1 2 3 4 5 6 7 8 9 10 1 2 6 24 120 720 5,040 40,320 362,880 3,628,800 Permutations with Some Objects Alike Sometimes not all of the objects to be permuted are distinct. For example, suppose we have 3, A’s, 4 B’s, and 5 C’s to be permuted, or 12 objects all together. There are not 12! permutations, since the A’s are not distinguishable from each other, nor are the B’s, nor are the C’s. Suppose we let G be the number of distinct permutations and that we have a list of these permutations.

066! 06523 Sampling here has had a dramatic impact on the average percentage of D items delivered ᭿ to the customer. This is just one example of how probability and statistics can assist in delivering high-quality product to consumers. There are many other techniques used that are called in general statistical process control methods, or SPC; these have found wide use in industry today. Statistical process control is the subject of Chapter 11. CONCLUSIONS We have explored permutations and combinations in this chapter and have applied them to several problems, most notably a plan for choosing the best candidate from a group of applicants for a position and acceptance sampling where we found that sampling does improve the quality of the product sold and actually puts a limit on the percentage of unacceptable product sold.
