The graphics command below builds a simple bull's eye. (I used it for a
probability question in my math class)  It does what I want it to, but with
all the repetition I know that it is probably possible to do it more simply.
 It isn't so long but I figured I could learn something by seeing how this
command could be duplicated in different ways.   I was looking at Thread but
couldn't quite manage to get things to work out.   The specific colors
aren't really important, but I did want to get each disk to be a different

Thanks for any suggestions you might have.
