12 1 Theoretical Probability Outcome the result of

12 -1 Theoretical Probability Outcome- the result of an experiment (rolling a 6) Probability- a measure of how likely an event is to occur Impossible outcome- an outcome that can never happen What is an impossible outcome for rolling a die? Certain Outcome- an outcome that will always happen What is a certain outcome for rolling a die?

As likely as not (50/50) Certain Unlikely Impossible 0 Likely 0. 5 You are rolling a die. 1. ) Name an impossible event. 2. ) Name an event that has 50% probability. 3. ) Name a certain event. 1
