North Carolina Standard Course of Study
NC.7.SP. Statistics and Probability
Investigate chance processes and develop, use, and evaluate probability models.
NC.7.SP.5. Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring.
NC.7.SP.6. Collect data to calculate the experimental probability of a chance event, observing its long-run relative frequency. Use this experimental probability to predict the approximate relative frequency.
NC.7.SP.7. Develop a probability model and use it to find probabilities of simple events.
NC.7.SP.7.a. Develop a uniform probability model by assigning equal probability to all outcomes, and use the model to determine probabilities of events.
NC.7.SP.7.b. Develop a probability model (which may not be uniform) by repeatedly performing a chance process and observing frequencies in the data generated.
NC.7.SP.7.c. Compare theoretical and experimental probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy.
