Probability I can predict appropriate probability of a given event using words and numbers

Essential Question What is probability? How do we represent probability?

Let’s review some words: Certain Equally likely Impossible Unlikely Likely Using each word, come up with events that would have that specific outcome.

Tell me... Impossible 1/2 Equally Likely 1 Certain Unlikely Likely What is the probability that the school bell will ring at 2:15 pm? What is the probability of getting heads or tails on a coin? What is the probability of getting a 7 on a 6 - sided game cube? Likely Equally likely Impossible
