Non-transitive Spinners
Based on task from nRich: http://nrich.maths.org/7541
Each player chooses a different spinner. The winner is the person whose spinner shows the bigger number.
Alison and Charlie are playing the game. Charlie wants to go first so Alison lets him.
Was that such a good idea?
Can you advise Alison on which spinner to choose once she knows which spinner Charlie has selected?
