Statistics and Probability
Cluster: Investigate chance processes and develop, use and evaluate probability models.
KY.7.SP.5. Describe the probability of a chance event is a number between 0 and 1, which tells how likely the event is, from impossible (0) to certain (1). A probability near 0 indicates an unlikely event, a probability around 1/2 indicates an event that is neither unlikely nor likely and a probability near 1 indicates a likely event. (MP.5, MP.6, MP.7)
KY.7.SP.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. (MP.1, MP.2)
KY.7.SP.7. Develop a probability model and use it to find probabilities of events. Compare probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy. (MP.4, MP.7, MP.8)
KY.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.
KY.7.SP.7.b. Develop a probability model (which may not be uniform) by observing frequencies in data generated from a chance process.
