The only memoryless discrete probability distributions are the geometric distributions, which count the number of independent, identically distributed Bernoulli trials needed to get one "success". In other words, these are the distributions of waiting time in a Bernoulli process. See more In probability and statistics, memorylessness is a property of certain probability distributions. It usually refers to the cases when the distribution of a "waiting time" until a certain event does not depend on how … See more Suppose X is a continuous random variable whose values lie in the non-negative real numbers [0, ∞). The probability distribution of X is memoryless precisely if for any non-negative real numbers t and s, we have See more With memory Most phenomena are not memoryless, which means that observers will obtain information about … See more Suppose X is a discrete random variable whose values lie in the set {0, 1, 2, ...}.
