See more. For instance, the first relative frequency of an occurrence is two out of 20 and the second relative frequency is five out of 20. Example 1: To check either the company is manufacturing good or defective bulbs. Let us find the relative frequency for the categories you see in the able above. What does relative frequency mean? Relative Frequency Examples: Here are the few examples that will explain the importance of relative frequency in probability problems. relative frequency. This will help you calculate relative frequency. a. the ratio of the actual number of favourable events to the total possible number of events; often taken as an estimate of probability.
