Standard: 7.SP.C.6

Domain: Statistics & Probability

Theme: Investigate chance processes and develop, use, and evaluate probability models

Description: 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.
