2. Empirical Probability Assignment
The Empirical or Relative Frequency Method
of assigning probability uses past data that
have been empirically observed. It notes the
frequency with which some event has
occurred in the past and estimates the
probability of its reoccurrence on the basis of
historic data.
3. Empirical Probability Assignment
P (X) = ƒ (X) / n
Where,
ƒ (X) = Number of times event X has
occurred in the past
n = Total number of observations
4. Empirical Probability
Empirical probability is based on observations obtained from
probability experiments. The empirical frequency of an event E is the
relative frequency of event E.
