Let’s Experiment!

Probability Activity Sheet

Spinner

  • If we spin our spinner TEN times what’s the probability of landing on:

    • Red?

    • Yellow?

    • Blue?

    • Green?

Spinner

  • If we spin our spinner HUNDRED times what’s the probability of landing on:

    • Red?

    • Yellow?

    • Blue?

    • Green?

  • How can we use our data to predict what would happen if we  spun the spinner:

    • 200 times?

    • 50 times?

    • 150 times?

Elaborate

Let’s Make Some Predictions!

Chart

If 25 more students were surveyed:

  • How many would you expect to choose hot dogs?

  • How many would you expect to choose hamburgers?

Evaluate

If 50 more students were surveyed, how many would you expect to choose pizza?
