ns without Repetition Problem: How many ways can 5 different books be arranged on a shelf? Solution: Total books (n) = 5 Number to arrange (r) = 5 (all books) Use permutation formula: \[ P(5, 5) = \frac{5!}{(5 - 5)!} = 5! = 120 \] Answer: There are 120 ways to arrange 5 books. Exam
20}{4} = 30 \] Permutations of Multisets When dealing with multisets (sets with repeated elements), the permutation count takes into account identical objects, as shown above. Binomial Theorem and Combinations The binomial theorem expands expressions like \( (a + b)^n \), involving combinations: \[
