Problem 5 5.a Consider the following identity. For all positive integers n and k with n 2k, (n choose k) + (n choose k-1) = (n+1 choose k). This can be demonstrated either algebraically or via a story proof. To prove the identity algebraically, we can write (n choose k) + (n choose k-1) = n!/[k!(n-k)!] + n!/[(k-1)!(n-k+1)!] = [(n-k+1)n! + (k)n!]/[k!(n-k+1)!] [n!(n+1)/k!(n-k+1)!] = (n+1 choose k). Which of the following is a story proof of the identity? Consider a...

1. What is wrong with the following proof that shows all integers are equal? (Please explain which step in this proof is incorrect and why is it so.) Let P(n) be the proposition that all the numbers in any set of size n are equal. 1) Base case: P(1) is clearly true. 2) Now assume that P(n) is true. That is for any set of size n all the numbers are the same. Consider any set of n + 1...
