Lesson 4: Probability
I Can...
...gather experimental data and compare experimental probabilities with theoretical probabilities.
...analyze and explain why theoretical and experimental probabilities could be different.
...calculate and represent experimental probabilities as fractions, decimals, and percents.
...investigate the likelihood of an event by gathering experimental data and finding the experimental probability.

Words to Know
Outcomes: possible results of a probability event
Simple Event: one outcome or a collection of outcomes
Probability: the chance that some event will occur
Random: if each outcome is equally likely to occur
Complementary Events: two events in which either one or the other must happen, but the cannot happen at the same time
Theoretical Probability: based on what should happen under perfect conditions
Experimental Probability: based on what actually happens in an experiment
