Outcomes

7.SP.C.7

Develop a probability model and use it to find probabilities of events; compare probabilities from a model to observed frequencies; and if the agreement is not good, explain possible sources of the discrepancy.

7.SP.C.7.A

Develop a uniform probability model by assigning equal probability to all outcomes, and use the model to determine probabilities of events.

7.SP.C.7.B

Develop a probability model (which may not be uniform) by observing frequencies in data generated from a chance process.
