Approximate the probability of a chance event by collecting data

7.SP.C.6

7.SP.C.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.

What you'll learn

  1. Define experimental probability as the relative frequency of an event observed in actual trials
  2. Compute experimental probability from collected data: P(event) = (number of times event occurred)/(total number of trials)
  3. Explain what "long-run relative frequency" means and why more trials produce more reliable estimates
  4. Predict approximate relative frequencies given a theoretical probability
  5. Compare experimental results to theoretical probabilities and explain sources of discrepancy
  6. Understand that experimental probability approaches theoretical probability as the number of trials increases
