It's a Tie
Why not create your own experiment? You could draw and cut out ties
(or print off this
sheet) and perhaps put them in a bag to be picked out.
Maybe you could create a simulation on the computer?
It might be a good idea to work with some friends in different
groups so that you have more results to look at.
Look at the results of your experiment. How many times did you pull
out the same tie in a week?
How does this compare with your friends' experiments?
