THEORETICAL + EXPERIMENTAL PROBABILITY

By:Tehya Pugh

What is Theoretical Probability Theoretical Probability Is what you

predict what will happen without really doing the experiment.

I have a number cube and a coin. What can you predict what you

would get if you tried 20 times with this experiment?

12 total outcomes.

What is Experimental Probability? Experimental Probability is when you

actually test your experiment. So if I actually tried my experiment

24 times, how many total outcomes could there be?

24 total outcomes.

5 questions Question # 1. What is the probability of rolling a 6 and

flipping a heads? 1/12 Question # 2. How many total possible outcomes are there? 12 Question # 3. What is the probability of flipping a heads and

rolling a 3 OR 5? 3/8 Question # 4. What is the probability of flipping heads OR

tails and getting a 6? 3/8 Question # 5. What is a probability of flipping tails and rolling

a 5,6 or 1? 4/8 or ½
