Introduction

We've just finished the chapter on Probability. Let's do a review to ensure we have mastered each topic.

Probability

In this chapter we covered the following topics:

  •  Theoretical probability as likelihood 
  •  Theoretical probability as a number 
  •  Experimental probability 
  •  Expected outcomes 
  •  Dependent and independent events 
  •  Probability of compound events 

Outcomes

7.SP.C.5

Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring. Larger numbers indicate greater likelihood. 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.

7.SP.C.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.

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.8

Find probabilities of compound events using organized lists, tables, tree diagrams, and simulation.
