Learning objectives

 * State that permutation is an arrangement and write the meaning of $${^{n}}P_{r}$$
 * State that $${^{n}}P_{r}$$=$$\frac{n!}{(n-r)!}$$ and apply this to solve problems
 * Show that
 * 1) $${(n+1)^{n}}P_{n}$$=$${^{n+1}}P_{n}$$
 * 1) $${^{n}}P_{r+1}$$=$${(n-r)^{n}}P_{r}$$

Learning objectives
and apply the result to solve problems
 * State that a combination is a selection and write the meaning of $${^{n}}C_{r}$$
 * Distinguish between permutations and combinations
 * Derive $${^{n}}C_{r}$$=$$\frac{n!}{(n-r)!r!}$$
 * Derive the relation $${^{n}}P_{r}$$=$${^{n}}C_{r} X r!$$
 * Verify that $${^{n}}C_{n}$$=$${^{n}}C_{n-r}$$ and give its interpretation
 * Derive $${^{n}}C_{r} + ^{n}C_{n-r}$$=$${^{n+1}}C_{r}$$ and apply the result to solve problems.
