Theoretical and Compound Probability Review

Even chance of event happening as not happening

• unlikely

• equally likely

• certain

• impossible

The chance an event will occur. It can be written as a fraction, decimal or percent.

• odds

• sample space

• outcome

• probability

A good way to organize outcomes for compound events would be..

• An outcome table

• box plot

• line graph

• put them in a hat and draw

Probability based on what "should" happen

• theoretical

• experimental

• tree diagram

• outcome table

What is the probability of spinning an even number?

• 16 2/3%

• 33 1/3%

• 50%

• 75%

What is the probability of spinning red?

• 0

• 1/2

• 3/4

• 1

A compound event is..

• an event that directly causes another

• the probability of all the outcomes

• 1 event that creates 2 results

• when 2 or  more independent events work together
