The tree Diagram shows all the possible ways three Candidates (A, B,C) could run for president and 4 candidates (1,2,3,4) Could run for Vice president.
Tell us all the possible outcomes we could have a new President and a new Vice President.
Example, A1,A2...
Closing: Using the simulation you did today in class and the tree diagram for the theoretical
Probability what conclusion can you make about the Theoretical Probability and the
Experimental Probability of an event occuring?

Definitions:
Theoretical probability is a method to express the likelihood that something will
occur. It is calculated by dividing the number of favorable outcomes by the total
possible outcomes. The result is a ratio that can be expressed as a fraction (like 2/5).
or a decimal 4, or percent, 40%
Experimental probability is probability that is determined on the basis of the results
of an experiment repeated many times.
