Group Activity Cards
Use groups of 4 or more.
Materials: Index cards, paper bag
| In the Bag
Each group member writes his or her name on an index card. Group members then place all of the cards in the same paper bag.
Determine the theoretical probability that any group member who draws a card from the bag without looking will get his or her own name. Then do the experiment. In turn, each group member selects a card, notes whether or not the name on the card is his or her own, then puts the card back in the bag. Group members should find and compare their experimental probabilities for drawing their own names after four, eight, sixteen, and twenty draws. What happens to the experimental probability as the number of draws increases?
