The chance that something will happen. How likely it is that some event will occur.

Sometimes we can measure a probability with a number like "10% chance", or we can use words such as impossible, unlikely, possible, even chance, likely and certain.

Example: "It is unlikely to rain tomorrow".

As a number, probability is from 0 (impossible) to 1 (certain).
