Chew on an activity for probability. Given information on the number of gumballs in a gumball machine, scholars consider how likely it is to randomly draw a blue gumball and how many of each color they would draw in 10 trials if the gumballs are replaced each time. They test their predictions using a paper cup and color chips, and then interpret the resulting data.
