probability determined by the relative frequency of occurrence of an event, or actual observations of an experiment is called ______ probability.
probability determined by the relative frequency of occurrence of an event, or actual observations of an experiment is called probability.

Explanation:

Empirical probability is calculated based on the relative frequency of an event's occurrence from actual experiments or observations. It contrasts with theoretical probability (which is based on mathematical models without conducting experiments). For example, if we flip a coin 100 times and get 45 heads, the empirical probability of getting heads is \(\frac{45}{100}=0.45\).

Answer:
