WebbConvergence in Mean. For a fixed r ≥ 1, a sequence of random variables X i is said to converge to X in the r t h mean or in the L r norm if lim n → ∞ E [ X n − X r] = 0. This is denoted by X n → L r X. For r = 2 this is called mean-square convergence and is denoted by X n → m. s. X. Mean convergence is stronger than convergence ...

What is the probability that at least half out of 100 newborns will be boys? To answer this question, let Xi = 1 if i-th newborn is a boy and Xi = 0 otherwise. Then Xi = 1 with probability p = 0:51 and Xi = 0 with probability 1 ¡ p = 0:49. Therefore „ = E[Xi] = 0:51 and¾2 = p(1¡p ...
