Standard SP.5 - Investigate chance processes and develop, use and evaluate probability models. Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring.
Standard SP.7 - Develop a uniform probability model by assigning equal probability to all outcomes and use the model to determine probabilities of events.
Standard SP.8.A - Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs.
Standard SP.8.B - Represent sample spaces for compound events using methods such as organized lists, tables and tree diagrams. For an event described in everyday language (e.g., "rolling double sixes"), identify the outcomes in the sample space which compose the event.
Standard SP.4 - Draw informal comparative inferences about two populations. Use measures of center and measuares of variability for numerical data from random samples to draw informal comparative inferences about two populations.
