Access Point #: MAFS.912.S-IC.1.AP.2b

Approximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability. For example, when rolling a number cube 600 times, predict that a 3 or 6 would be rolled roughly 200 times, but probably not exactly 200 times.
Clarifications:

Essential Understandings

Concrete:

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

    Table with column headers of Number of tosses, Number of heads, and Probability of heads with corresponding data underneath in five rows.
General Information
Number: MAFS.912.S-IC.1.AP.2b
Category: Access Points
Date Adopted or Revised: 06/14
Cluster: Understand and evaluate random processes underlying statistical experiments. (Algebra 2 - 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.
