TOPIC IX: PROBABILITY – 7 TH GRADE
Chapter 9: Lesson 1 – Probability of Simple Events
Probability is the ______________ that an event will occur. A simple ________________ is an outcome or a collection of _______________. An outcome is what ____________________ happens.
Why
Probability is written as a ratio that compares the outcomes of the event to the possible outcomes. P(event) =
Topic 9: Probability Page 1
What is the P(red) P(blue) *P(not blue) P(red or green)
*Complementary event: event that can’t occur at the same time. Usually has the word _________. Both events total ____________.

Chapter 9 – Lesson 2: Theoretical and Experimental Probability
In a ______________________________________, there is an equal probability for an outcome to occur.
If I was the owner of a gameshow, which wheel would be better for me to use? Explain.
Which one would the players like to use? Explain.
Theoretical vs. Experimental
Theoretical – what should happen, what I am _________________ (based on ______)
Experimental – what actually happens, __________ the experiment (based on _______)
Topic 9: Probability Page 4
Compare the theoretical to the experimental.
Theoretical:
Experimental:

Chapter 9: Lesson 3 and 5 – Probability of Compound Events and Counting Principle
Compound Events consists of ______________ or more simple events. One event does __________ affect the other. The probability of compound events can be found by making lists or _____________________. It will give you the ______________________, all the possible outcomes.
Probability of compound events can also be found using the Counting Principle, _____________________________. The counting principle will give you the total number of outcomes. Then I multiply the favorable outcomes.
