  2. Event (probability theory) - Wikipedia

    en.wikipedia.org/wiki/Event_(probability_theory)

    An event, however, is any subset of the sample space, including any singleton set (an elementary event), the empty set (an impossible event, with probability zero) and the sample space itself (a certain event, with probability one). Other events are proper subsets of the sample space that contain multiple elements. So, for example, potential ...

  3. Double counting (fallacy) - Wikipedia

    en.wikipedia.org/wiki/Double_counting_(fallacy)

    Double counting can be generalized as the fallacy in which, when counting events or occurrences in probability or in other areas, a solution counts events two or more times, resulting in an erroneous number of events or occurrences which is higher than the true result. This results in the calculated sum of probabilities for all possible ...

  4. Lewis's triviality result - Wikipedia

    en.wikipedia.org/wiki/Lewis's_triviality_result

    Lewis (1976) pointed out a seemingly fatal problem with the above proposal: assuming a nontrivial set of events, the new, restricted class of -functions will not be closed under conditioning, the operation that turns probability function into new function () = (), predicated on event 's occurrence.

  5. Universal probability bound - Wikipedia

    en.wikipedia.org/wiki/Universal_probability_bound

    Universal probability bound is then used to argue against random evolution. However evolution is not based on random events only ( genetic drift ), but also on natural selection . The idea that events with fantastically small, but positive probabilities, are effectively negligible [ 2 ] was discussed by the French mathematician Émile Borel ...

  6. 100 prisoners problem - Wikipedia

    en.wikipedia.org/wiki/100_prisoners_problem

    Probability distribution of the length of the longest cycle of a random permutation of the numbers 1 to 100. The green area corresponds to the survival probability of the prisoners. In the initial problem, the 100 prisoners are successful if the longest cycle of the permutation has a length of at most 50.

  7. Birthday problem - Wikipedia

    en.wikipedia.org/wiki/Birthday_problem

    Let these events be called Event 2, Event 3, and so on. Event 1 is the event of person 1 having a birthday, which occurs with probability 1. This conjunction of events may be computed using conditional probability: the probability of Event 2 is ⁠ 364 / 365 ⁠, as person 2 may have

  8. Gambling mathematics - Wikipedia

    en.wikipedia.org/wiki/Gambling_mathematics

    The mathematics of gambling is a collection of probability applications encountered in games of chance and can get included in game theory.From a mathematical point of view, the games of chance are experiments generating various types of aleatory events, and it is possible to calculate by using the properties of probability on a finite space of possibilities.

  9. Probability space - Wikipedia

    en.wikipedia.org/wiki/Probability_space

    The probability measure is a set function returning an event's probability. A probability is a real number between zero (impossible events have probability zero, though probability-zero events are not necessarily impossible) and one (the event happens almost surely, with almost total certainty).
