## Probability

The language of probability

Probability is about working out how likely or probable something is going to happen. To be able to use probability in problem solving, you first need to understand the language. Some common words used in this topic include:

Possible outcomes: what could occur in a given event or experiment.

Successful outcomes: a possible outcome that meets the criteria for success.

Sample space: a set of all possible outcomes that could occur in a given event or experiment.

Event: the trial of an experiment (it also has a probability).

Independent events: the probability of each event is not influenced by each other.

Dependent events: the probability of each event is directly influenced by each other.
