Proving the lack of memory property of the Geometric distribution

Web(c) If for a random variable X,P (X > t) = P (X > t +s ∣ X > s), we call it memoryless. Justify this name. Is exponential distribution a memoryless random variable? Previous question Next question This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Weberty of geometric random variables. The idea is that we start with (and often use) the fact that, if Xis exponential with E(X) = 1= , then P(X>a) = e a for a>0. The idea of the memoryless properly, for example, is that P(X>14 j X>8) = P(X>6) Intuitively, thinking about the fact that exponential random variables are waiting times, this new theory about what causes ibs https://bdmi-ce.com

Webrandom variable Tis necessarily memoryless for otherwise the Markov prop-erty, whereby assuming the knowledge of the current state the knowledge of the past is irrelevant to predictions about the future, will be violated. It is a standard result in elementary probability that the only memoryless continu-ous random variables are exponentials. Webi be the random variable corresponding to the number of days between tagging of the i-th and (i + 1)-th animal. Note if i animals have already been tagged, the probability of capturing an untagged animal is 1 − i/n. Hence, P(T i = 1) = 1 − i/n, and in general, P(T i = k) = (1 − i/n)(i/n)k−1. That is, T i is a geometric random variable for WebThe geometric distribution is considered a discrete version of the exponential distribution. Suppose that the Bernoulli experiments are performed at equal time intervals. Then, the geometric random variable is the time (measured in discrete units) that passes before we obtain the first success. Contrast this with the fact that the exponential ... midway museum address
