1.A factory produces 10 glass containers daily. It may be assumed that there is a constant probability p=0.1 of producing a defective container. Before these containers are stored they are inspected and the defective ones are set aside. Suppose that there is a constant probability r = 0.1 that a defective container is misclassified. Let X equal the number of containers classified as defective at the end of a production day. (Suppose that all containers which are manufactured on a particular day are also inspected on that day.) Compute P(X=2)=? a. 0.1937 b. 0.1714 c. 0.2541 d. None of above. 2. What is the required discrimination of a comparator given a tolerance of 0.005 and an accuracy ratio of 10:1? 第一題的答案 參考書好像是選 D 因為 C10取2*0.01^2*0.99^8 = 0.00415 可是我是選 B 因為 C10取2*0.09^2*0.91^8 = 0.1714 第二題的題目在寫什麼 有人可以解釋嗎 英文每個字都懂 組起來就不懂...>< --
