• Experimental Probability

• Theoretical Probability

What type of probability is a way of estimating the probability of an event happening based on repeated trials?

• Experimental Probabillity

• Theoretical Probability

What is the formula for calculating probability?

• Favorable outcomes × total outcomes

• Favorable outcomes ÷ total outcomes

• Total outcomes ÷ favorable outcomes

• Favorable outcomes - total outcomes
