Hello everyone, tell me, please, can someone already have a ready-made formula for calculating the probability of guessing a password / promo code / pin code and so on?

Combinatorics
Find the number of combinations, multiply by the search speed - you get the maximum time for which the password will be guessed - that is, the probability of guessing will be equal to 1.
The guessing probability for another period of time will be inversely proportional to the maximum time.
