What is Probability?
Probability is a measure that we use to tell how likely an event or outcome is.

When do we use probability?
We use probability any time we want to know how likely something is to happen.

How do we write probabilities?
We can write probabilities as fractions. The numerator is the number of ways the event can occur. The denominator is the number of possible events that could occur.
Probabilities can also be expressed as percentages.
