Use tree diagrams, frequency tables, organized lists, and/or simulations to collect data from a two-step simulation of compound events (using two coins and/or two dice).

Clarifications:

Essential Understandings

Concrete:

  • Use items like coins to determine the probability of an outcome (1/2 heads).
  • Using manipulatives and a chart to capture the outcomes of coin flips or dice rolls.
Representation:
  • Identify the formula for finding probability of an event (probability of an event happening = number of ways it can happen/total number of outcomes)
  • Use a chart to capture the outcomes of coin flips or dice rolls.
  • Understand the concepts, symbols, and vocabulary for: probability, likelihood.

Date Adopted or Revised: 06/14 Cluster: Investigate chance processes and develop, use, and evaluate probability models. (Supporting Cluster) : 

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Name Description
MAFS.7.SP.3.8: Find probabilities of compound events using organized lists, tables, tree diagrams, and simulation.
  1. 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.
  2. 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.
  3. 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?
