What describes classical probability?

• Probability that can be calculated using theory, like flipping a coin, drawing a card, or rolling a die.

• Probability that can be calculated once an experiment has been done that has provided resulting data.

• Probability that can be calculated using someone's educated guess based on previous observations or future estimations.
