Match the following probability types to their definitions.

• Experimental probability

• What we think is going to happen based on math when we do something like flip a coin

• What actually happened based on our data

• Theoretical probability

• When two events do not change each other's probability

• Dependent probability

• When one event changes the entire probability space for the next event
