# Experiments to determine how likely an outcome is

I can determine the likelihood of an outcome by designing and carrying out an experiment.

## Lesson details

### Key learning points

- An experiment can be designed to determine how likely an outcome is.
- An experiment can be carried out and the outcomes recorded.
- The outcomes can be considered and the likelihood of each outcome stated.

### Common misconception

A small number of trials in an experiment is enough to provide conclusive findings.

Even in situations where we know that the different outcomes of a trial are equally likely happen, one outcome may happen more often than the others. E.g. when we flip a coin 10 times, we don't always get the exact same number of heads and tails.

### Keywords

Experiment - An experiment is a repetition of a trial multiple times in order to observe how often each outcome occurs.
