QIA Suppose that the probability of finding defectives within a manufactured lot of electrical fuses is 0.2. Assume the probability distribution is binomial. Let X be the number of defectives within the sample. In a sample of 16 fuses, find the probabilities (a) P(X-2), (b) PX22), (c) P(1 ≤X<3). B Suppose the discrete random variable X has the probability distribution listed in the table below. Find: (a) P(11 < X < 15). (b) E(4X-7).
