MAFS.7.SP.3.6

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.
Subject Area: Mathematics

Domain-Subdomain: Statistics & Probability
Cluster: Level 2: Basic Application of Skills & Concepts
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.

SAMPLE TEST ITEMS (2)

  • Test Item #: Sample Item 1
  • Question:

    A spinner is divided into equal parts 1-5. George spun the spinner 300 times. A table of outcomes is shown.

    Based on the table, what is an estimated probability of the spinner landing on an even number?
