2. Relative Frequency
The relative frequency of an event is defined as the
number of times that event occurs during
experiments.
3. Relative Frequency
• In most events, it is difficult to accurately predict the
probability of an event happening.
• When there is no theory behind the probability of an event
happening, we use Relative Frequency to calculate
probabilities
• Because it is often calculated after performing experiments,
it is often called Experimental Probability
4. Relative Frequency
• The probability of picking a vegetarian at random from a
group of people can be found using relative frequency
• The easiest way to calculate this probability is by conducting
an experiment.
