objective probability and empirical probability

what is the definition of that? Thanks.

Empirical probability involves establishing the probability using past, or historical data. If a subjective probability involves personal judgement, would objective probability use methods that do not require personal judgement? In other words, would that mean Empirical and Priori probabilities fall under the larger class of “objective probability”?

Priori = logical Analysis Empirical= Relative Frequency of occurance Objective = mix of both, objectives do not vary from person to person Subjective=Personal judgement can change from person to person
