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...

What is wrong with the following proof that every positive integer equals the nex larger positive integer? "Proof," Let P(n) be the proposition that n = n + 1, Assume that P(k) is true, so that k = k + 1 . Add 1 to both sides of this equation to obtain k + 1-k + 2 . Since this is the statement P(k 1), It follows that P(n) is true for all positive integers n.

11: I can identify the predicate being used in a proof by mathematical induction and use it to set up a framework of assumptions and conclusions for an induction proof. Below are three statements that can be proven by induction. You do not need to prove these statements! For each one clearly state the predicate involved; state what you would need to prove in the base case; clearly state the induction hypothesis in terms of the language of the proposition...

23. Let Pr be the following statement: Every group of n persons that contains at least one male contains only males. What is wrong with the following proof by induction that this statement is true for all n? Certainly P is true. Now assume that Pr is true, and take any group of n+1 persons containing at least one male. Let G pI,p2sp3,..Pa Prt denote this group, with pi being the known male. The subgroup (pi,p2,p3,... n) of G...
