Cards and Independence | This problem solving task lets students explore the concept of independence of events. |

Interactive Marbles | This online manipulative allows the student to simulate placing marbles into a bag and finding the probability of pulling out certain combinations of marbles. This allows exploration of probabilities of multiple events as well as probability with and without replacement. The tabs above the applet provide access to supplemental materials, including background information about the topics covered, a description of how to use the application, and exploration questions for use with the Java applet. |

Rain and Lightning | This problem solving task challenges students to determine if two weather events are independent, and use that conclusion to find the probability of having similar weather events under certain conditions. |

Return to Fred's Fun Factory (with 50 cents) | The task is intended to address sample space, independence, probability distributions and permutations/combinations. |

Spinner | In this activity, students adjust how many sections there are on a fair spinner then run simulated trials on that spinner as a way to develop concepts of probability. A table next to the spinner displays the theoretical probability for each color section of the spinner and records the experimental probability from the spinning trials. This activity allows students to explore the topics of experimental and theoretical probability by seeing them displayed side by side for the spinner they have created. This activity includes supplemental materials, including background information about the topics covered, a description of how to use the application, and exploration questions for use with the java applet. |

The Titanic 2 | This task lets students explore the concepts of probability as a fraction of outcomes and using two-way tables of data. |
