Could anyone please explain or give me example about priori probability?
It’s “a priori” probability.
Given a coin you’ve never tossed before, the a priori probabilities you assign to tossing heads and tossing tails will likely be \frac12 and \frac12, respectively.
Given a die you’ve never rolled before, the a priori probabilities you assign to rolling 1, 2, . . ., 6 will likely be \frac16, \frac16, . . ., and \frac16, respectively.

A priori probability is based on logical analysis.
If there is you + 4 friends competing over 1 ticket show, there is a 20% probability that you’ll win
It’s pure logical/deductive reasoning
And certain assumptions, such as assigning equal probabilities to congruent outcomes.
