Title: Thinkport | Probability and Tree Diagrams
URL: https://aptv.pbslearningmedia.org/resource/mmpt-math-ee-intsurvey2/probability-and-tree-diagrams/
Description:

Use a tree diagram to find the probability that a set of triplets will be all girls in this interactive from MPT. In the accompanying classroom activity, students find the probability of various outcomes of compound events involving a set of dice, such as the probability of rolling doubles and the probability of rolling at least one “2.” They share solution strategies, including methods of representing sample spaces for these compound events. To get the most from the lesson, students should have experience developing and using uniform probability models. For a longer self-paced student tutorial using this media, see "Tree Diagrams" on Thinkport from Maryland Public Television.

Title: Grade 7 Mathematics Module 5, Topic B: Estimating Probabilities
Description:

In Module 5, Topic B, students move to compare probabilities from simulations to computed probabilities that are based on theoretical models (7.SP.C.6, 7.SP.C.7). They calculate probabilities of compound events using lists, tables, tree diagrams, and simulations (7.SP.C.8). They learn to use probabilities to make decisions and to determine whether or not a given probability model is plausible (7.SP.C.7). The Mid-Module Assessment follows Topic B.
