WebbX is tight means that for all ǫ > 0 there is an M for which P(kXk > M) < ǫ. {Xn} is uniformly tight (or bounded in probability) means that for all ǫ > 0 there is an M for which sup n P(kXnk > M) < ǫ. (so there is a compact set that contains each Xn with high probability.) 25 WebbIt can be written as the ratio of the number of favorable events divided by the number of possible events.
