How do we think about events in our daily lives? How much of it happens by chance? Can we predict any of it?

In the activity Approximate the Probability of a Chance Event students examine the relationship between expected events and the events that actually occur. They look at the expected probability of an event such as rolling a 3 on a number cube and then actually perform the experiment to see if what they get is the same, or even close to what is expected.


Students use different models like flipping coins, spinning spinners, and of course, rolling number cubes in this activity. They come to realize that as the number of trials increase, the probability in the experiment gets closer to the one they had expected. This is a dynamic activity which allows students to explore this concept in a way that they could not do by simply using a textbook.
