Probability - is the likelihood or chance of an event occurring.

Probability = Favorable outcomes/possible outcomes

eg. flipping a coin - probability 50% because there's two sides

Probability - can be expressed as a ratio, fraction or percent

eg. rolling dice - you have 1/6 chances of getting any number on the die

Outcome - one possible result of a probability experiment

- what might happen

Favorable Outcome - a successful result in a probability experiment

- what we want to happen
