Warm-up
Your teacher will give your group a bag containing slips of paper with names on them. It is important not to open the bag to reveal all of the slips at any time. Record your group's data in writing.
Follow these steps to collect data about the names in the bag:
- Shake the bag, then draw out only 1 slip of paper.
- Read the name you drew out loud so that everyone in the group can keep track of the results in the table.
- Return the slip of paper to the bag and pass the bag to the next person in the group.
- Repeat these steps until each person in the group has had a chance to draw at least 3 names or the group has drawn at least 15 times.

- How many times did your group draw a name from the bag?
- What name did you draw most frequently?
- For the name you drew most frequently, estimate the probability of drawing that name on the next draw.
