Relative frequency is defined as the number of times an event occurs during experiments and is used to calculate probabilities when theoretical predictions are difficult. It is often referred to as experimental probability, particularly useful in scenarios without a predetermined theory. An example includes calculating the probability of selecting a vegetarian from a group by conducting an experiment.

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.
