When should we keep our free coffee card? When should we bet it?
- Teacher noteOffer students a couple of scenarios. What would they do if only one other person's card in the bowl was competing with theirs for the prize? What would they do if 10,000 other people's cards were competing? So where is the number of people where you'd switch your decision?
- Teacher noteTake this opportunity to introduce your students to the concept of expected value.
