Advanced Mathematics problem

Need help in the following proof problem. may need theorem or definition. (See attached file for full problem description) --- Definition of Binomial Coefficient: Given a set X and a non-negative integer r, an r-subset of X is a subset A X of cardinality r. We denote the set of r-subsets of X by Pr(X), i.e. Pr(X) = {A X | |A| = r}. We define the binomial coefficient or binomial number ( n, r) (read 'n choose r') to be the cardinality of the set Pr(X) when |X| = n. The binomial Theorem: For all real numbers a and b and non-negative integers n, (a+b)n = n Sum (n, a(n-i) b(i) i=0 i) = an + …+ (n, a(n-... click for more
