Experimental and Theoretical Probability

What is the difference between theoretical and experimental probability?

• Experimental Probability is what should happen while Theoretical Probability is what does happen.

• Theoretical Probability is what should happen while Experimental Probability is what does happen.

• There is no difference.

• One is a fraction and one is a decimal.
