Unformatted text preview: Find the probability a part has at least one defect. Given: event A = { part has defect A } P( A) = .10 Find Prob of at least one defect 7 Given: P( A) = .10 P( B) = .05 P(AB) = .02 Find: E ={at least one defect} = AB P(AB) Apply the addition rule: P (A B) = P(A) + P(B)  P(A B) Example: Two components in parallel 8 Given Component & System data The probability A works is 0.88 The probability B works is 0.71 The probability both work is 0.68 Find the probability the system works Given: P(A) = 0.88 P(B) = 0.71 Example: Analyze the results of inspected parts 9 Parts can have two types of defects, A and B. A sample of 150 parts are inspected an the results are shown below: Define notation; consider a randomly selected Defect B yes no Defec t A yes 5 10 no 15 120...
