Using a single coin, find a fair way to select the presenter.
There are a variety of possible methods. Make sure each student has an equally likely chance of being selected.
What is the smallest number of coin tosses needed to select a presenter fairly? Describe the method.
Draw a tree diagram.
How many times does the coin need to be flipped to get a sample space of
equally likely outcomes?
Two of the group members realize they won’t be in class the day of the presentation because they are playing in a baseball tournament. Can a presenter still be chosen fairly with a single coin? Explain why or why not?
Yes. Explanations/methods will vary.
