occurring. Larger numbers indicate greater likelihood. A probability near 0 indicates an unlikely event, a probability<br />
7.SP.5<br />

its long-run relative frequency, and predict the approximate relative frequency given the probability.<br />

frequencies; if the agreement is not good, explain possible sources of the discrepancy.<br />

probabilities of events.<br />
b. Develop a probability model (which may not be uniform) by observing frequencies in data generated from a chance process.<br />
Find probabilities of compound events using organized lists, tables, tree diagrams, and simulation.<br />
a. Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample<br />
space for which the compound event occurs.<br />
b. Represent sample spaces for compound events using methods such as organized lists, tables and tree diagrams. For an event<br />
described in everyday language (e.g., "rolling double sixes"), identify the outcomes in the sample space which compose the<br />
event.<br />
