Скачать или смотреть Using A Tree Diagram - Probability | 7.SP.C.8 | Grade 7 Math 💚💙

In this math video we will be using a tree diagram to determine the number of different combinations possible for desired outcomes. We will learn how to read a tree diagram showing probable outcomes. We will use the tree diagram to answer questions by identifying specific outcomes. We will review how to apply the Fundamental Counting Principle to a tree diagram to determine the total number of combinations. An exemplar solution is modeled and explained.

Probability
Investigate chance processes and develop, use, and evaluate probability models.
7.SP.C.8 Find probabilities of compound events using organized lists, tables, tree diagrams, and simulation.
7.SP.C.8.a Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs.
7.SP.C.8.b Represent sample spaces for compound events using methods such as organized lists, tables and tree diagrams. For an event described in everyday language (e.g., “rolling double sixes”), identify the outcomes in the sample space which compose the event.
7.SP.C.8.c Design and use a simulation to generate frequencies for compound events. For example, use random digits as a simulation tool to approximate the answer to the question: If 40% of donors have type A blood, what is the probability that it will take at least 4 donors to find one with type A blood?
