you choose blue or purple
if a spinner lands on the colour you chose you win that amount
which region would you pick for this picture?
- if the spinner stops on purple and you have chosen it, you get $200
- if it stops on blue and you have chosen it you get $100
- if it stops on the other colour to the one you chose, you lose
an image from Dan (on Vimeo) sets up the problem:
where/when would you stop choosing the purple?
elsewhere, there is a 'Geogebra' programme that simulates the spinning
