For a given transition rate, i.e., a Q-matrix Q = (qij) on a countable state space, the uniqueness of the Q-semigroup P(t) = (pij(t)), the recurrence and the positive recurrence of the corresponding ...

Classical probability theory assumes an equal likelihood for all outcomes. For example, if you were to flip a coin, there's an equal change of it landing on "heads" or "tails." Microsoft Excel offers ...
