WebbLet the probability of a newborn being a boy be, say, 0.51. 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 ... WebbIn this part we will go through basic de nitions, Continuous Mapping Theorem and Portman-teau Lemma. For now, assume X i2Rd;d<1.
