Experimental Probability Lesson

Experimental Probability is:

• What Will happen 
• What actually happens
• What should happen
• What I think Happens

Which of the following describes theoretical probability?

• a. Perform an experiment to determine the probability

• a. Determining the expected probability of an event

• a. Perform a simulation and count the number of possible outcomes

• a. Use trials to count the number of desired outcomes
