Math 103 Chapter One Part Two – Election Methods I Chapter One – The Mathematics of Voting and Elections – Part Two There are different methods of determining the winner of an election. We are going to look at several of them and discuss how fair they are. The first method is known as the Plurality Method Plurality Method – the candidate with the most first place votes win. This is a very easy to calculate method, and when it comes to elections, this is the method that most people think of. If there are two candidates running, then one of them will have a majority (or there is a tie), but with more than two candidates, a majority might not happen. Remember the pizza example? # of votes 4 3 2 1 st Choice P M S 2 nd Choice S S M 3 rd Choice M P P Pepperoni wins with 4 votes, but 5 is needed for a majority. Note that 5 people rank pepperoni in last place. This doesn't seem entirely fair that pepperoni wins. We compared each candidate in a head-to-head election, and here were the results: Pepperoni vs Sausage: P = 4, S = 5

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
