How to Construct a Relative …1.2.1 Long run relative frequency. One of the oldest documented 4 problems in probability is the following: If three fair six-sided dice are rolled, what is more likely: a sum of 9 or a sum of 10? Let’s try to answer this question by simply rolling dice and seeing if a sum of 9 or 10 happens more frequently. Relative frequency = event count/total count. Since we divide how many times the event occurs by the total number of events that occurred, the frequency of the event is relative to the total number of events.
