Equiprobable measure
From CS2800 wiki
The sample space for a six-sided die example had the property that every simple event had the same probability.
If this is the case, we say that the probability measure is equiprobable.
WARNING: Not every probability measure is equiprobable! Do not assume this unless you have a good reason!
With an equiprobable measure, one can compute the probability of any event by just counting the number of elements of :
