In a set of data, if an event has a relative frequency of 0.25, what does this mean?
The event happened 25 times.
The event is very unlikely.
The event occurred in 25% of the trials.
The event is certain to happen in the future.

Relative frequency, as described, is how often the event has occurred in those trials. If the frequency is 0.25, that means the event has happened in 25% of those situations.
