Inclusion Exclusion: The inclusion-exclusion principle, combinations with repetition, and derangements. WebCombinatorics, by Andrew Incognito. 1.11 Newton’s Binomial Theorem. We explore Newton’s Binomial Theorem. In this section, we extend the definition of (n k) ( n k) to allow n n to be any real number and k k to be negative. First, we define (n k) ( n k) to be zero if k k is negative. If n n is not a natural number, then we use α α instead ...
