CO.7.3. Data Analysis, Statistics, and Probability
7.3.2. Mathematical models are used to determine probability. Students can:
7.3.2.a. Explain that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring. (CCSS: 7.SP.5)
7.3.2.b. 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. (CCSS: 7.SP.6)
7.3.2.c. Develop a probability model and use it to find probabilities of events. (CCSS: 7.SP.7)
7.3.2.c.i. Compare probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy. (CCSS: 7.SP.7)
7.3.2.c.ii. Develop a uniform probability model by assigning equal probability to all outcomes, and use the model to determine probabilities of events. (CCSS: 7.SP.7a)
