Chance Experiments


Activity #1

Chance experiment.

  • You’ll need a sheet of paper and pencil for this activity.​
  • Click 10 times on the Spin button below. Make sure to wait for the arrow to stop before you spin again.​
  • Add the numbers under occurrences to confirm that it is 10. That is the total number of trials.​
  • Express the occurrence of each color as a fraction of the total number of trials.​
  • Also express the occurrence of each color as a percentage.​
  • Perform many more trials as possible to master the concept.

Activity #2

Play Game of Chance.

The applet below displays a random number from 1 to 6, like a number cube. With a partner, you will play a game of chance.

  • In the first round, one of you will score on an even roll and one of you will score on an odd roll. You decide that first.
  • In the second round, the winner of round 1 will score on numbers , and the other player will score on numbers .
  • Each round is 10 rolls. Be sure to turn on “History” after your first roll and wait for it to update before rolling again.

(1.) When each player had three numbers, did one of them usually win?

(2.) When one player had four numbers, did you expect them to win? Explain your reasoning.

Activity #3

Classify Events on a Probability Scale.

Below are some cards that describe events.

  • Order the events from least likely to most likely.
  • After ordering the first set of cards, add the new set of cards to the first set so that all of the cards are ordered from least likely to most likely.

Challenge #1

Label each event with one of these options: impossible, unlikely, equally likely as not, likely, certain

Challenge #2

Different events have the following likelihoods. Sort them from least to greatest:
